Last week a bear grabbed my brothers day pack from the Lone Pine campground around 2 am. I woke up and scared the bear off by simply saying "hey" twice, but not before the bear had inflicted significant damage to the pack and its contents. The worst damage was my brother's glasses, which got a tooth mark in them. Apparently, there was some residue from an energy gel that had leaked in the pack and on the glasses case.
Bears are active in the area. I think the moral of the story is to think of things that have come into contact with food and that that valuables should not be left in something a bear may be tempted to grab.
