OMG!!!!!!! i thought that had fail written all over it.
Sorry but I dont think I would be trying this any time soon. Now dont get me wrong but it just looks like a huge bag of FAIL.
... i could see how they could get their hands on the bungee cords and harness, but when a group of young adults calls a constructing company to pour concrete and lay those giant towers id start asking questions. Id laugh my *ss off when they would say "well, were tying a couple of bungee cords to em and strappin his girlfriend in between them, yank her back to that barn with a 4wheeler and see what happens!"
