A friend of mine who doesn't do the outdoor thing sent me this regarding the difference between black and grizzly bears and the use of "bear" bells and bear spray.

" Outdoors men should recognize the difference between black bear and grizzly bear scat:
Black bear scat is smaller and contains lots of berries and squirrel fur.
Grizzly bear scat is larger, has little bells in it, and smells like pepper."

A little dark humor for the outdoor set ;)
