my harness is hooked before i go one inch up that tree, while on stand, and all the way down. even a fall from only a few feet can cause injury if you aren't prepared for the landing. i fell from a tree when i was about 12, only about 6 feet up and shattered my left elbow. spent about 10 weeks in casts, etc. now i'm 31 and every time i hold mybow to shoot, oruse my climber, i'm reminded of it cuz itbends and works a little differently than normal. so i have a constant reminder to use my harness.besides the fact that i have a wife, kids, and much more to life to think about losing or ruining over the sake ofa few minutes of my time. i already have one lifelong reminder, i don't want any more.
