[together] HELLO, MR.

CONDUCTOR!

- I WONDER IF YOU REMEMBER WHERE WE'RE GOING TODAY.

[together] NATURE TRACKERS ADVENTURE CAMP!

[cheering] - VERY GOOD!

YOU REMEMBERED.

- HOW COULD WE FORGET?

AN ADVENTURE CAMP FOR NATURE TRACKERS WITH ALL MY FAVORITE FRIENDS COMING ALONG?

IT CAN'T GET ANY BETTER THAN THIS!

- IT COULD.

TODAY I'M GONNA HAVE SOME EXTRA HELP FROM ANOTHER FRIEND OF YOURS: MY NEPHEW GILBERT.

- GILBERT?

- GOOD MORNING, EVERYBODY.

all: GILBERT!

- IS IT TIME TO SING THE SONG, UNCLE?

all: A SONG?

SING IT!

- WELL, I GUESS THERE'S AN ADVENTURE CAMP SONG, BUT YOU PROBABLY DON'T WANT US TO SING IT.

all: AH, COME ON.

SING IT.

PLEASE?

WE'VE ARRIVED.

ADVENTURE CAMP RIVER STATION IN THE LATE CRETACEOUS TIME PERIOD.

ALL RIGHT, NATURE TRACKERS.

FORM A LINE.

GILBERT AND I WILL BE LEADING YOU ON YOUR ADVENTURE.

- TODAY'S ADVENTURE IS... RIVER RAFTING!

[together] RIVER RAFTING?

- FOLLOW ME, KIDS.

- MR.

CONDUCTOR, WHAT EXACTLY IS RIVER RAFTING?

- WE'RE GOING TO FLOAT DOWN THE RIVER ON RAFTS MADE OF LOGS.

- WE'LL LEARN ABOUT HOW RIVERS WORK AND WHAT KIND OF CREATURES CAN BE SEEN AS WE FLOAT BY.

- THEN THE DINOSAUR TRAIN PICKS US UP AT A STATION DOWN THE RIVER TO TAKE US HOME.

- AFTER A GREAT BIG PICNIC LUNCH, OF COURSE.

- UM, WILL THERE BY FOOD FOR HERBIVORES LIKE ME?

- ABSOLUTELY, TANK.

THERE'LL BE SOMETHING FOR EVERYONE.

- THOSE MUST BE OUR RIVER RAFTS.

LET'S GO, NATURE TRACKERS.

WHOO!

- WAIT, WAIT, MISS TINY.

FIRST WE PUT ON OUR SAFETY GEAR.

- RIGHT.

EVERYONE GETS A HELMET.

- NOW, SINCE PTERANODON SWIM IN THE SEA EVERY DAY, YOU THREE WON'T NEED LIFE JACKETS, BUT EVERYONE ELSE GETS 'EM.

ANNIE, PETEY, LILY, TANK, AND BUDDY.

- WAIT, WILL I HAVE TO SWIM IN THE RIVER?

- NOT IF I CAN HELP IT.

THE LIFE JACKET'S JUST IN CASE YOU FALL OFF THE RAFT.

- BUT I'M A T. REX.

I'M NOT REALLY A SWIMMER.

AM I GOING TO BE OKAY?

- AS YOUR ADVENTURE CAMP GUIDE, I PROMISE YOU'LL BE OKAY.

I'LL BE RIGHT BY YOUR SIDE THE WHOLE TIME.

NOW IT'S TIME TO CHOOSE A BUDDY, SOMEBODY FOR YOU TO KEEP AN EYE ON FOR SAFETY WHILE WE'RE RAFTING.

[together] A BUDDY?

I PICK BUDDY!

[laughter] - SORRY, KIDS.

BUDDY CAN ONLY PICK ONE BUDDY.

- I PICK ANNIE.

- YEAH!

I'M BUDDY'S RIVER RAFTING BUDDY.

RAWR!

- THEN I PICK PETEY, 'CAUSE WE BOTH HAVE... both: TINY POWER!

WHOO-HOO!

- I PICK DON 'CAUSE HE KNOWS SO MANY THINGS.

- I PICK SHINY 'CAUSE WE'RE BOTH BLUE.

- UM, ACTUALLY, I WAS HOPING I COULD BE GILBERT'S BUDDY.

- SORRY, SHINY.

I CAN'T BE A BUDDY.

I'M STEERING THIS RAFT, AND UNCLE CONDUCTOR IS STEERING THE OTHER.

- CAN TANK AND I RIDE ON YOUR RAFT, GILBERT?

- ABSOLUTELY HOP ONBOARD.

- [squawks] COME ON, TANK, MY RAFTING BUDDY.

splash!

- EVERYONE READY?

ALL ABOARD!

GET OUT YOUR PADDLES, EVERYONE.

TWO ON EACH SIDE.

THAT'S RIGHT.

STROKE, STROKE, STROKE.

all: STROKE, STROKE, STROKE.

- WOW, WE'RE REALLY OUT IN THIS RIVER.

I WONDER HOW DEEP IT IS.

- HOW YOU DOING, BUDDY?

- OKAY.

IT'S PRETTY EXCITING DOING SOMETHING I'VE NEVER DONE BEFORE.

I GUESS IT'S A LITTLE SCARY TOO.

- NEVER FEAR, BUDDY, MY BUDDY.

THAT'S THE THING ABOUT ADVENTURES.

THEY HELP US FIND THE COURAGE TO TRY NEW THINGS.

- REALLY?

WHERE DO YOU FIND THE COURAGE?

- WELL, I FIND IT INSIDE MYSELF.

I TELL MYSELF THAT I CAN DO WHATEVER I PUT MY MIND TO.

AND IF I KEEP TELLING MYSELF THAT, I FIND MY COURAGE.

- OKAY, MR.

CONDUCTOR.

I'LL TRY HARD TO FIND MY COURAGE.

RAWR!

- OOH, RAWR.

- LOOK AT THAT, PETEY!

LET'S MAKE OUR RAFT THE FASTEST.

READY?

both: TINY POWER!

[squawking] - WHERE DO RIVERS COME FROM?

- A RIVER STARTS AS A TINY STREAM MADE OF RAIN WATER LIKE THAT LITTLE STREAM OVER THERE.

THE STREAM CUTS DOWN INTO THE EARTH AND CARRIES THE SEDIMENTS, OR DIRT, DOWNSTREAM.

THIS PROCESS IS CALLED EROSION.

[together] EROSION.

- WHAT DID HE SAY?

ERASER?

EXPLOSION?

- EROSION.

- OH.

- AND AS MORE AND MORE LITTLE STREAMS FLOW INTO ONE RIVER, IT GROWS BIGGER AND BIGGER.

OUR LITTLE RIVER IS JOINING A BIGGER RIVER NOW.

[together] OOH!

A BIGGER RIVER.

- SEE HOW THIS BIGGER RIVER CUTS THROUGH THESE HILLS?

OVER TIME, RIVERS CHANGE THE LAND BY CARVING NEW PATHS FOR THEMSELVES.

SO IF THE RIVERS CARVE OUT THE LAND, WHERE DOES ALL THAT DIRT GO?

- SOMETIMES, RIVERS CARRY SO MUCH DIRT DOWNSTREAM, THEY CAN BUILD A WHOLE NEW PIECE OF LAND.

HERE'S WHAT WE CALL A SANDBAR.

THIS IS DIRT AND SAND THAT THE RIVER CARRIED DOWN AND DEPOSITED HERE.

- AND NOW, IT'S A HABITAT, A HOME TO MANY PLANTS AND CREATURES THAT ARE SPECIALIZED FOR LIVING IN THE WATER.

- HELLO!

WE'RE THE NATURE TRACKERS.

all: HELLO.

- NATURE TRACKERS OBSERVE NATURE, SO WE'RE OBSERVING YOU.

all: OH.

THANK YOU VERY MUCH.

- WHOOPS, THE RIVER'S CARRYING US AWAY.

GOT TO GO.

BYE.

[birds squawk] - BYE.

- THINK I'LL HAVE A LITTLE FUN.

[laughs] - [squawks] I'M GETTING HUNGRY.

ARE YOU, PETEY?

- YEAH.

I WONDER WHAT WE'RE GONNA HAVE FOR LUNCH.

- I HOPE IT'S FISH.

WHEN I GET HUNGRY, YOU KNOW WHAT I SAY?

I WISH FOR FISH!

[squawks] BONUS!

- OH, YOU GUYS?

DID YOU SEE THAT?

TINY DID SOME KIND OF MAGIC TRICK.

- WHAT DID YOU DO, TINY?

- I DON'T KNOW.

I JUST SAID, "I WISH FOR FISH."

AND-- JUST LIKE THAT!

- [laughs] - HEY, EVERYBODY!

TINY'S DOING A MAGIC TRICK!

- I WISH FOR FISH.

[kids cheering] WAIT A MINUTE.

THIS IS A LITTLE TOO GOOD TO BE TRUE.

I DON'T THINK I'M ACTUALLY MAGIC.

SO WHAT'S HAPPENING?

[gasps] JESS HESPERORNIS.

- [laughs] YOU GOT ME, TINY.

HI, EVERYONE.

I'M JESS, A HESPERORNIS.

- HESPERORNIS IS A CREATURE THAT'S WELL-ADAPTED TO LIVING IN THE WATER.

- I AM.

- I THOUGHT YOU DID YOUR FISHING IN THE SEA.

WHAT ARE YOU DOING IN THIS RIVER?

- HEY, THERE'S FISH IN THE SEA AND IN RIVERS, TINY.

AS LONG AS IT'S WET, I'M PRETTY MUCH GOOD.

- WELL, YOU'RE WELCOME TO JOIN US FOR LUNCH WHEN WE GET TO THE PICNIC AREA, JESS.

- REALLY?

THAT SOUNDS LIKE FUN.

- IT WILL BE, BUT FIRST, WE HAVE TO RUN A SET OF RAPIDS.

- OOH, RAPIDS!

MY FAVORITE!

- WAIT A MINUTE.

WE HAVE TO RUN A SET OF RAPIDS?

WHAT DOES THAT MEAN?

- ANOTHER OPPORTUNITY TO LEARN ABOUT HOW RIVERS WORK, BUDDY.

AS A RIVER CONTINUES TO FLOW DOWNHILL, SOMETIMES THEY FLOW STEEPLY ENOUGH TO MAKE BIG WAVES AND EVEN WATERFALLS.

- WATERFALLS?

- OH, THESE RAPIDS ARE PRETTY SMALL, BUDDY.

THEY WON'T BE LIKE GOING OVER A BIG WATERFALL.

- I'M NOT SURE I WANT TO GO OVER EVEN A LITTLE WATERFALL.

- OH, BUDDY, YOU ARE GONNA LOVE THIS.

RUNNING THE RAPIDS IS MY FAVORITE THING TO DO.

I'LL SWIM RIGHT ALONG SIDE YOU GUYS AND KEEP YOU COMPANY.

- RAWR.

- FIND YOUR COURAGE, BUDDY.

RAWR!

- OKAY, EVERYONE, PADDLES READY!

KEEP THE RAFTS MOVING FORWARD!

STEER DOWN THE MIDDLE OF THE RIVER.

LET'S GO, NATURE TRACKERS.

all: STROKE, STROKE, STROKE, STROKE, STROKE.

WHOA!

- WHOO-HOO-HOO-HOO!

[all screaming excitedly] [all cheering] - WELL, WHAT'D YOU THINK?

- THAT WAS THE MOST FUN THING I'VE EVER DONE EVER!

WHEN DO WE GET TO RIDE THE NEXT ONE?

- WE'RE ALMOST AT THE PICNIC SPOT FOR LUNCH.

- AW, ALREADY?

MR.

CONDUCTOR, WHEN I FOUND MY COURAGE, I HAD SO MUCH FUN.

- I AM SO PROUD OF YOU, BUDDY.

AND I'M PROUD OF ALL YOU KIDS FOR PADDLING THE RAFTS ALL THIS WAY.

LUNCHTIME!

[all cheering] - [squawks] MM, I DON'T REMEMBER WHEN I'VE HAD SO MANY FISH.

- I KNOW, RIGHT?

- BUT WHAT ABOUT THE TROODONS?

WHAT DID YOU AND GILBERT EAT, MR.

CONDUCTOR?

- AS OMNIVORES, WE HAD A LITTLE BIT OF EVERYTHING, BUDDY.

- YUP, I'LL PRETTY MUCH TRY ANYTHING.

[belches] [laughs] EXCUSE ME.

[train whistle toots] - WHOOPS.

THAT'S THE DINOSAUR TRAIN.

TIME TO GO HOME, KIDS.

WALK THIS WAY.

[belches] [laughter] - OH, MR.

CONDUCTOR!

- ALL ABOARD!

all: BYE, JESS!

- SEE YOU AROUND WHEREVER THERE'S FISH.

HEY, NICE JOB FINDING YOUR COURAGE, BUDDY!

BYE!

WHEN WILL GILBERT AND THE CONDUCTOR TELL US WHERE WE'RE GOING FOR CAMP TODAY?

- I HOPE IT'S SOMEWHERE PRETTY.

- WITH LOTS OF GREAT FOOD.

- AND HOLES.

- HELLO, NATURE TRACKERS.

all: HELLO, MR.

CONDUCTOR.

HI, GILBERT.

- GOOD MORNING.

- READY FOR TODAY'S ADVENTURE?

all: YES!

- BECAUSE WE'RE HEADED TO NATURE TRACKERS ADVENTURE MOUNTAIN CAMP.

all: MOUNTAIN CAMP?

- YES, INDEED-Y.

WE'RE HEADING TO THE TOP OF THAT MOUNTAIN.

all: OOH.

- WON'T IT BE HARD TO GET ALL THE WAY UP THERE?

- NOT FOR ME.

I'LL FLY UP AND BE KING OF THE MOUNTAIN!

- KING OF THE MOUNTAIN?

I LOVE THAT GAME.

- ME TOO.

I'M GREAT AT THAT GAME.

- THEN THAT'S WHAT WE'LL PLAY.

- WE WON'T BE FLYING THERE EITHER TO BE FAIR TO THE CAMPERS WITHOUT WINGS, SO WE'LL ALL HIKE.

GILBERT?

- MOUNTAIN HIKING TIPS: AS WE CLIMB, THE AIR WILL GET COLDER AND THE WIND WILL BLOW HARDER.

IF YOU FIND IT A LITTLE MORE DIFFICULT TO BREATHE, DON'T WORRY BECAUSE THIS IS NORMAL.

YOU'LL BE ABLE TO BREATHE.

IT'S JUST HARDER WHEN YOU'RE HIGH UP.

- AT HIGH ALTITUDES, BECAUSE THERE'S LESS OXYGEN, WHICH IS THE GAS WE BREATHE.

- THANK YOU FOR LISTENING, AND ENJOY YOUR VISIT TO THE TOP OF THE MOUNTAIN.

- GILBERT, IS THERE ANYTHING SPECIAL WE SHOULD LOOK FOR ON THE HIKE?

- I'M SO GLAD YOU ASKED.

ON THE WAY UP, WE'LL BE LOOKING FOR THE TREE LINE.

- THAT'S RIGHT, GILBERT.

OBSERVE.

THE TREE LINE-- OR TIMBERLINE-- IS A POINT HIGH ON THE MOUNTAIN WHERE THE TREE AND BUSHES ARE AFFECTED BY THE COLD, THE WINDS, AND THE ALTITUDE.

NOW, CAN ANYBODY GUESS HOW THE TREES ARE AFFECTED?

- MAYBE THE TREES AND BUSHES HAVE MORE DELICIOUS LEAVES BECAUSE HERBIVORES NEED MORE FOOD AFTER CLIMBING UP ALL THAT WAY.

- INTERESTING GUESS, TANK.

ANY OTHERS?

- I HAVE A HYPOTHESIS.

MAYBE SINCE THE MOUNTAIN GETS TALLER AND TALLER, THE TREES AND BUSHES DO TOO.

SO THE TREES WAY UP AT THE TIMBERLINE MUST BE REALLY, REALLY TALL.

- GUESS THERE'S ONLY ONE WAY TO FIND OUT, BECAUSE WE'VE ARRIVED AT ADVENTURE CAMP MOUNTAIN STATION.

ALL OFF-BOARD!

[all cheering] - [squawks] THERE IT IS!

THE TOP OF THE MOUNTAIN.

- AND SOON, WE'LL ALL BE THERE WITH ME LEADING THE WAY!

♪ DA, DA-DA, DA ♪ CHARGE!

- EASY, THERE, SHINY.

I LOVE YOUR ENTHUSIASM, BUT BEFORE WE GO STORMING UP THE MOUNTAIN, LET'S SEE WHAT'S AROUND US RIGHT HERE.

- WELL, THE TREES HERE ARE REALLY TALL.

- THAT'S TRUE.

THEY'RE-- - WAIT.

DON'T TELL US.

MM, JUICY.

LIGHT AND FRUITY AT FIRST...

FOLLOWED BY A HINT OF NUTTINESS.

IT'S A SYCAMORE.

- HE'S VERY GOOD AT THAT.

- TANK KNOWS HIS LEAVES.

- [sniffs] MY T. REX SNIFFER SENSE SAYS THERE ARE MAMMALS HERE.

DO YOU SMELL THEM, BUDDY?

- [sniffs] I DO.

OH, AND THERE'S ONE.

- [squeaking] - IT'S SO TINY AND CUTE.

- EXCELLENT OBSERVATIONS, EVERYBODY.

- YEAH, GREAT, SO NOW CAN WE GO TO THE TOP OF THE MOUNTAIN?

PLEASE?

- I THINK SO, SHINY.

NATURE TRACKERS ADVENTURE CAMPERS, LET'S START HIKING!

- ME TOO, AND I'VE GOT REALLY THICK SKIN.

- COME ON, GUYS.

WE CAN'T STOP NOW.

WE'RE SO CLOSE TO THE TOP.

- I KNOW HOW TO GET US CLOSER AND KEEP US WARM.

RUN!

- [squawks] LAST ONE TO THE SNOW PATCH IS A ROTTEN DINOSAUR EGG!

[laughter] - OH, OOH, THIS IS HARD.

[giggling and panting] - I WON!

I WON THE RACE.

[together] WE ALL MADE IT!

- BUT SHINY MADE IT FIRST.

GOOD JOB.

- THANKS.

- [pants] YOU GUYS...

WERE RIGHT.

I'M ALL WARMED UP NOW.

- ME TOO.

BUT IT'S A LITTLE HARD TO BREATHE.

- UM... WHY?

- GILBERT, ON THE TRAIN YOU SAID IT'S HARD TO BREATHE BECAUSE THERE'S LESS OXYGEN SO HIGH UP.

- RIGHT.

NICE JOB REMEMBERING, BUDDY.

- OH, I AGREE.

VERY GOOD, BUDDY.

[pants] - [laughs] LOOK, MR.

THE CONDUCTOR IS LEANING ON THE TOP OF A TREE.

- THAT'S FUNNY.

ALL THE TREES ARE SMALL HERE.

THERE'S JUST A LITTLE BIT TALLER THAN ME, AND I'M TINY.

- AND LOOK.

A LINE OF TREES... AND NO MORE TREES ABOVE IT.

THIS MUST BE THE TREE LINE.

kids: THE TREE LINE.

- EXACTLY RIGHT, KIDS.

WE'VE OFFICIALLY REACHED THE TREE LINE.

DO YOU NOTICE ANYTHING ABOUT THE AREA?

- I DO.

THERE'S NO PLANTS EXCEPT THESE SCRAGGLY LITTLE SHRUBS.

- THAT'S TRUE, TANK.

THEY ARE LITTLE AND SCRAGGLY.

ANYBODY THINK THEY KNOW WHY?

- MAYBE THE REASON TRESS CAN'T GROW TALL IS BECAUSE THAT'S HOW THINGS GROW WAY UP HIGH ON A MOUNTAIN WHERE IT'S SO COLD AND WINDY.

- YOU ARE EXACTLY RIGHT, BUDDY.

THE DIFFERENT WEATHER AT HIGH MOUNIN ALTITUDES MAKES THINGS GROW DIFFERENTLY.

- YAY, BUDDY!

YOUR HYPOTHESIS WAS TRUE.

♪ LA, LA, LOO-- ♪ - I MIGHT BE TOO COLD UP HERE FOR TREES TO GROW TALL, BUT IT'S NOT TOO COLD FOR A SNOWBALL FIGHT.

RIGHT, BUDDY?

- [laughs] RIGHT.

HEADS UP, TINY.

- INCOMING!

[kids whooping and cheering] - OOH!

- OH, YES.

SNOWBALL FIGHTS.

I REMEMBER BACK IN MY DAY, I WAS QUITE THE CRACKERJACK.

NOW, OF COURSE, I AM MUCH MORE RESPONSIBLE AND SOPHISTICATED.

I COULDN'T POSSIBLY-- WHOA!

AH!

OOH!

- COME PLAY WITH US, MR.

CONDUCTOR.

kids: YEAH!

COME ON.

PLEASE?

- GANGWAY!

[all whooping and cheering] - HEY, YOU GUYS?

WE'RE SO CLOSE TO THE TOP OF THE MOUNTAIN.

SO I WAS THINKING, IF NO ONE MINDS, I COULD JUST RUN UP TO THE MOUNTAINTOP.

I'LL BE RIGHT WHERE YOU CAN SEE ME.

BUT I WON'T GO IF IT'S NOT OKAY WITH EVERYBODY FOR ME TO BE... KING OF THE MOUNTAIN.

[pants] I DID IT.

I'M HERE.

I MADE IT!

I'M KING OF THE MOUNTAIN!

ACTUALLY, QUEEN OF THE MOUNTAIN.

- HEY, SHINY DID IT.

SHE GOT TO THE TOP OF THE MOUNTAIN.

[kids cheering] - [pants] NICE JOB, SHINY.

YOU'RE A CREDIT TO THE NATURE TRACKERS ADVENTURE MOUNTAIN CAMPERS.

- THANKS, GILBERT.

- WOW, LOOK AT THE VIEW.

all: WOW.

- I THINK I CAN SEE MY HERD FROM HERE.

- I THINK I CAN SEE THE ENTIRE CRETACEOUS FROM HERE.

- IT'S BEAUTIFUL.

THANKS FOR GETTING US ALL UP HERE, SHINY.

- HOORAY FOR SHINY.

- QUEEN OF THE MOUNTAIN.

all: YEAH!

- GO SHINY!

- ALL RIGHT!

- THANKS.

I REALLY WANTED TO GET TO THE TOP FIRST, BUT IT'S WAY BETTER LOOKING AT THE VIEW WITH ALL OF YOU.

- THAT'S WHAT IT SAYS IN THE NATURE TRACKERS ADVENTURE CAMP GUIDEBOOK: BEING AN ADVENTURER IS ALL ABOUT TEAMWORK.

- YOU GUYS ARE THE BEST TEAM EVER.

- I FEEL A GROUP HUG COMING ON.

COME HERE, YOU.

- I LOVE YOU ALL SO MUCH.

- I LOVE YOU GUYS.

- SPEAKING OF TEAMWORK, THINK YOU KIDS COULD HELP ME UP?

[pants] - ARE YOU OKAY?

- OH, RIGHT AS RAIN, BUDDY.

JUST A LITTLE, UH, POOPED FROM THIS THIN MOUNTAIN AIR.

- WE'LL HELP YOU, MR.

THE CONDUCTOR.

WAIT, HOW DO WE HELP MR.

THE CONDUCTOR?

- I HAVE AN IDEA.

ONE, TWO, THREE.

PUSH!

- AND PULL!

- [squawks] WE DID IT.

all: YEAH, WE DID IT.

- OH, YOU CERTAINLY DID.

I FORGOT JUST HOW DIFFERENT LIFE IS ABOVE THE TREE LINE.

THE THINNER AIR CAN REALLY MAKE YOU SHORT OF BREATH.

WHOO, THANKS FOR ALL YOUR HELP, NATURE TRACKER ADVENTURE CAMPERS.

- DO WE HIKE BACK DOWN THE MOUNTAIN NOW?

- ACTUALLY, WE'VE ARRANGED A MORE INTERESTING WAY TO GET BACK DOWN.

[rumbling footsteps] all: LAURA GIGANOTOSAURUS.

- [pants] HELLO, NATURE TRACKERS.

GUESS WHAT.

I AM YOUR SURPRISE SPECIAL RIDE DOWN THE MOUNTAIN AND BACK TO THE DINOSAUR TRAIN.

[all cheering] - THANKS, LAURA.

THAT WAS THE MOST FUN RIDE EVER.

- YOU COULD SAY SHE GAVE YOU A HEAD START TOWARDS THE TRAIN.

[laughs] DO YOU GET--'CAUSE-- NO?

[clock chiming] OH, WOULD YOU LOOK AT THE TIME.

CAMP IS OVER FOR THE DAY, AND IT'S TIME TO GET BACK ON THE TRAIN.

ALL ABOARD!

all: THANKS, LAURA.

- IT WAS MY PLEASURE, NATURE TRACKERS.

WE ALL WORKED HARD.

NOW WE CAN REST ON THE TRAIN.
