lol..............I agreethere is one extreme hobby i would like to try its a combination of jumping off cliffs and sky diving.... its when you climb up the mountain and you ware this wing suit that allows you to have a feeling of flying for 20 seconds or so then pull a shuit.. ITs a glider suit and man I heard its a rush.
For the longest time you used to have to have an insane number of skydiving jumps before you'd even be allowed to buy the glider suits...I'm sure it's probably different since it's using base jumping and that's still considered illegal in most countries...
But I'd get in as many skydive jumps and base jumps as you can before you plan on trying this...
Nice thing is with enough skydive jumps you CAN get a glider suit to use in a regular skydive jumps fairly easily..
