My local field is a single speedball course consisting of spools, tires, and various other wooden bunkers. They are starting to get worn out, and some of the bunkers are falling apart. I've been talking to the field owner, and brought up the topic of Sup Air. He said he's been thinking about it, but is not sure if it would be worth it. Anyone have pricing on Sup Air fields? My buddies and I might chip in with the field owner, since we always play for free.
