its not really heights that im afraid of, just fear of falling and being out of controll of it, i learned the hard way last year, using what seemed like a sturdy branch, used this branch like 20x then one day about 10ft up snap and im on my back, left and went got me a safety strap, 1st-2nd day of gun season, had my SS on and fell again this time only about 2ft, but every stinkin bone in my back cracked and knocked the wind outta me basically those who dont use safety cautions are asking for trouble!
