there are some sick spots at rutgers university, busch campus in piscataway. I always eyed em up but never got to try em. you would definitely need some ply to lay down the first set of stairs for a runway. that is, if you dont have a portable drop in. you can see part of them at the bottom of this picture
on that note, heres the edit i just made for them- http://www.youtube.com/watch?v=AWxl8Yu6ZkY&feature=recentu
