Rigid Concrete Roof
Concrete is a very strong material. You've built a sturdy dome over the park -- but there's one big problem. The grass is dying!

Rigid roof + Concrete = Caution

The concrete roof blocks the sunlight, so the grass is turning a sickly shade of brown. The same thing happened to the grass in the Houston Astrodome, the first domed stadium in the United States. To make the brown baseball field look better for television, work crews painted the dirt green. Eventually, the dirt was replaced with an artificial grass called Astroturf.

Unfortunately, the Char County Flames hate Astroturf. It hurts their knees and it ruins their uniforms. You don't want to listen to their complaints, so you decide to try a different dome option.
