I had a similar instance as procraft with a Summit Viper. I started hunting from the ground of course so when I got a tree stand it was all new. I hunted several times out of my stand and all was well. One morning I was a few minutes late getting into the woods so I hurried up the tree. You can get high pretty fast in a Summit. However; I forgot to tie the bottom platform to the seat. I determined that my platform was looking down too far so I perched on the seat and raised the front of the platform to tighten my cable. Guess what happened next? The whole bottom half fell all the way to the ground!So I carefully bear hugged the big white oak and slid the best I could to the ground. Next problem?????? My seat section was still 35-40 feet in the tree and I was feeling pretty stupid. I re-attached my lower platform on the tree and used my lanyard on the safety belt as a climbing belt and to my dis-belief, I made it back up the tree. I was shaking, sweaty, and the insides of my arms and legs had a good tree burn on them. I don't think I hunted all that long that particular Saturday. The lesson here was not only to have a safety harness, but to slow down and pay attention to the details and not just race up the tree.
