Hey y'all,
I Have had one close call in 14 years of hunting. When I was 15 I cut my hand to the bone (across the palm) with a Bear Razorhead and passed out. When I came to, I was hanging upsidedown by my leg about 25 feet off the ground. I guess God looks out for fools because the only thing that kept me from falling to the ground was the strap (that held the top piece to the bottom piece) that my leg got tangled in. Thankfully I was able to haul myself back up.
After that I always used a harness and wouldn't climb without it.
