Rumor has it that one is coming to Hunter Mountain.
Here is a video from Whistler.
My fraternity used to set a small one up each year right before a new school year. Would set it and a couple repell lines up at Red Rock Canyon, OK. Was pretty small and redneck but was fun none the less. Went from the top to the hitch of my pickup truck. If the rope got a little slack in it, just pull the truck up. lol
