It's kind of a moot point for me. I haven't hung food since 1998.
Thirty years ago we would be camped at some nice lake in Yosemite, and the backcountry rangers would come around just before dark to see who had done it right and who had done it wrong. There would be a quiet pause for about an hour or so. Then the sounds would start up from the next lake over. We could hear people banging pots and pans, trying to scare off one of Yosemite's finest. I could almost set my watch by it, because I knew I had about an hour before the bear made it up to where my group was camped. I always had the group food bags up in the same tree, and two of us guys would have our sleeping bags around the trunk of the tree. That bear was going to have to come through us in order to climb the tree. It was all good fun.
Needless to say, the bear never scored against us. For the beginners at the next lake, it was not so easy. Many would have lost their food, but the rangers made them clean up after the bear the next morning. That's one thing that you really don't want to be forced to do, clean up after a bear, especially if that was your last food.
