On a recent hike on the AT I had what I assumed was a visit to my tent from a bear during the night. Came crashing through the trees and bushes and started whacking at a tree that was right beside the flap of my tent. I was petrified for what seemed like an eternity but was probably only 2 or 3 mins. When I got out of the tent in the morning there was large chunks of bark from the tree all around my tent. Does any one know why the (assumed bear) acted in such a way?
