It isn' t even the falling that bothers me. It is hitting the ground going really fast that I don' t like. I used to only be willing to climb up as high as I was willing to fall. About ten feet. But now I use my safty harness every time and climb weel over 20 feet without a problem. I am still carefull but I trust myself and my safty equipment. If I didn' t, I would stay a lot closer to the ground.
