. . . certainly burning corn cobs, steak bones and the like would cut down on trash that would attract Mr. Bear. If you don't have the luxury of a fire pit you can go with minimalist washing of cooking/dining gear if keeping garbage would otherwise be a lure for Mr. Bear . . .
Don't count on burning trash to keep bears away. The fire pit at our family cabin in Northern Minnesota regularly gets torn up by black bears looking for food scraps and we have big, hot fires.
The biggest thing I like about the beagle pre-wash is it eliminates food scraps from the grey water, of which I seldom have any because of the excellent job Simon does. I'm not worried about attracting bears as much as skunks and raccoons. If bleach doesn't kill what Simon leaves on the plate I'm not sure I would want to have him around.
