theres a tight DFD behind the union theater on campus.  kinda small and mellow, but looks like a mad fun rail.
I think me and some friends are gonna bring my drop in back there some night and some turf and since its right on the lake bring some buckets for water and see if its possible to hit in the summer time as well.
if it goes good we'll definately do it again and some of you guys in the madison area can meet us there for a sesh.
