Went on a group camping trip/hang over the weekend. I remember walking around looking at setups, and remarking to a buddy "I wouldn't hang off that tree, it's dead". I figured, hey... he probably shoved the tree to make sure it felt solid, HYOH and all that.
I won't name who hung this hammock, but as the rest of us were gathered around the group/campfire area, he got in his hammock to add a layer of long underwear pants. We all heard a crash:
The hanger was unhurt, and was still working his way out of the hammock as I took these quick cellphone pics.
I consider this a "near death" event. I don't know why the tree didn't fall directly into the other tree he was hanging from, but if it had I imagine the result would have been horrific. We all take our chances when we hang hammocks from trees, but try to make good decisions regarding tree choice, and as for me... "If you see something, SAY something!"
