Once in an icestorm - a Live hemlock next to me just fell down - I quickly got out of the hemlock I was in!
Probably the worst thing that happened to me was I was in a tree on a windy day - and back in the day my stand had no seat ( baker type stand). As I had done many times in the past - I sat myself in the "Y" of the tree where it branched just above my stand. On this windy day - the trees swayed - and the two limbs moved together and absolutely compressed my pelvis! The pain was awful and I was completely STUCK until they moved apart. I was lucky there was no serious damage and never again will I sit in the fork of a major tree!
