Zip-line
Weeks and weeks of planning. Days of drawing up plans and finding a likely venue. Hours and hours of hard labour.

Yes - when I was in the Scouts we designed and built a zip-line, fashioned from a couple of felled trees and a very, very long piece of rope.

The intended result:
A likely Scout would climb a rope ladder to the top, grab hold of the pulley-arrangement and whizz back to ground level at high speed down the rope.

Actual result:
- The whole contraption collapsing on top of our mini-bus, destroying both completely and utterly TO DEATH
- Greebo leaping 20 feet from the top, straight into a pile of cow shit
- Dozens of Scouts fleeing for their lives whilst crying out for their mothers
- Long, quiet walk home in the dark

Then I took a job in IT and found out how to REALLY fuck things up

We built a zip line once in Scouts
But I don't think the Scout leader had done it before, and didn't realise how tight the rope had to be.
First person down and the rope stretched and he ended up in the river.

Years later I built some with people who knew what they were doing and they were ratcheted taut, then we had to 'test' them several times to stretch the rope so it could be tightened more so the kids didn't get grass burn when they landed :D

last time i went on a zip line
it was a small one in a kid's park. i was also pissed and it was 3 a.m.
halfway along, my arse hit the ground. my pants were pulled down over my buttocks, i was flipped over and got tangled, upside down, in a giggling heap on the floor.
it was great fun!
