I think OS has the right idea.
Bears have a pretty big range but are smart enough to go back to areas they have found food in.

One of the first things I do when scoping out a campsite is look in the firepit. Lot's of unburnt or half burnt garbage makes me hesitate unless it's just to nice a spot to pass up.

Bear/wolf scat is part of that natural world, I'd rather find a fresh pile of that than a field of Turd Blossom's any day.  >:( :P :P
