I would agree with AKSAR. While the potential hazards of bears should be recognized, falls and drowning are far more common causes of death, although you wouldn't know that from internet discussions and news reports.

One of the easiest ways to avoid bear trouble is to keep a clean camp and secure all food-like items. One of the very best back country camps I have ever experienced was in Denali NP (I believe the location was known as Sunshine Pass)- beautiful weather and a gorgeous sunset. We were mindful because grizzlies had been reported from the spot just the day before. We clean up , cooked away from the tent, stowed our food at still another spot, and enjoyed Alaska.
