i have had the same thing happen to me. i was using a tree lounge and i didnt have the bottom part which is the slimbing aid attatched to the top part. i was wabout 30 feet up and my climbing aid slipped and it fell all the way to the bottom. luckily i had my cell phone. I called my brother and he came out to were i was with a rope. he unlatched one side of the climbing aid so i could pull it up the tree. he tied one end of the rope to climbing aid and threw the other end to me. i pulled it up and somehow got the climbing aid wrapped around the tree and got down safely. it was a stupid move. i will always have it tied now. like MOTOWNHONKEY said it is best not to panic. but im 15 years old and it was hard not to but everything was easier when i did.
