In the spring of 1997, naturalist Charlie Russell and artist Maureen Enns became foster parents of three wild grizzly bear cubs whose mother had been killed by a hunter. Enns stresses neither she nor her partner threw caution to the winds. However, the risks of approaching a wild animal are real.

Still, the risks are real. In 1996, for instance, prominent wildlife photographer Michio Hoshino, a veteran grizzly observer, was killed by a 7-year old Kamchatka bear that had become used to eating at a garbage dump and thus lacked the wild bear’s instinct to avoid people.
