Backyard Boarding from We're People Too!
About 12 minutes into the movie We're People Too, there is a contraption that you can put in your back yard that you climb up, strap in on, and then slide down so that you get speed to go off rails, boxes, jumps, etc. Its made of metal, approx. 6 feet high, and looks shady as f*** but if you have any ideas what its called, where you can get plans, who made that one, i'd appreciate. I'm sure they aren't mass produced but I'm lookin to make one thanks.
