Hang food and keep a clean camp. Carry bear spray can be more effective than a pistol it you don't shoot all the time. Don't buy the crap at wal mart it shoots five feet not 35 like its suppose too. If your really paranoid buy an ice fishing alarm and string fishing line thru the pull pin and circle it around camp. If something comes in the pin pulls out and alarm goes off loud as hell.... Hopefully scaring off bear.
