Sounds great to be honestI really want try
I had some friends that liked to rock climb and would play this game were they put on a harness and threw the rope around the limb of a very high tree and stack/climb box crates in a single width tower as tall as they could manage.
We had a very rarely used freight railway near us, so someone built a "death swing" which was basically some construction rope tied to a tree on one of the slopes next to tracks. You would hold onto the rope and just swing out, come back, bang into the hill
I wasnt there but one day a kid we knew tried going to the top of the hill for maximum velocity but let go halfway down. He was heading for the tracks, stuck his hands out, broke both wrists on impact with the track. We were 13 or 14 then
