All the noobs get wound up of bears. I've been been going into the California wilderness for 16 years, during that time I have seen 5 bears...3 in the wilderness and 2 in town and campground. One in Whitney Portal, another in June Lake dumpster diving, two in Ice House Canyon and one a 1/4 mile above Onion Valley Campground....and I don't think I'm atypical to the low side.

The issue concerning food in the Sierra is the small critters...marmots and chippies. They are the only varmints who have ever taken any of my wonders of modern science.
