You been watching too many Alaska bear movies. There's nothing that big around here and NONE are carnivores. :thefinger:A hungry 1200lbs bear is also no force to be wreakind with.
We did the whole Tahoe Rim Trail and didn't see a single bear. Like LD says, tie your pack high up in a tree. And put all your food in one pack. No food or smelly stuff - colognes, perfumes, etc in the tents, those also attract bears. The way people get hurt is being between the bear and what it's after.
Freeze dried food is where it's at for long trips, it's lightweight.
