Why would anyone shave a bear? and how can you do that and survive?
Bah! Anyone could get away with that...
I, however, was involved in sticking a cold metal spoon up the rear end of several bears on a cold snowy day in February while standing in knee-deep snow. I'm pretty sure those bears will be holding a grudge against people for a while...
The trick to any of those stunts is to make sure that one member of your group is slower than you. Even if it means tripping them.
