There is no official disc golf course in SRB. I tried to get one at Topsail State Park last year, but they declined due to not having enough room?? I'm pretty sure they don't understand the game, and that trees are usually hazards in the game, and that no tree would be harmed in the construction of a course. (Disc golfers+trees= tree huggers)...
You can go back up to Freeport and there is a course in the Hammock Bay Subdivision.
Or......make it a mission to get a course here locally. Visit our wonderful state parks and trails...check it out. Good luck!
