I'm a recent convert to bear bagging. Bears are not at all common where I hike. But raccoons and various rodents are common. I'm more concerned about my pack getting chewed through by rodents than I am about bears.

I found that hanging a bear bag is an easy habit to get into. It's second nature now. I don't bother with the PCT method or anything. Just throw the foodbag over a branch and tie it off. I sleep better knowing that my food and my pack are safe.
