This is a neat thread.
Carolina Downs near Kershaw, SC would fit well into the dog track category, which I say with affection.
Pebblebrook Golf Club near Manchester, Ga. is a very fun nine holer built by the late Arthur Davis, who did some solid courses in Georgia. You take a left at the barn that has PEBBLEBROOK painted on the side. The opening tee shot defies who knows how many rules of golf architecture and simple prudence, but if you pull it off it's pretty cool. I walked recently for the best 5 dollars of entertainment allowable. The pro shop is a mobile home where the owner seems to live, but there's also a decent pub there.
Recently abandoned golf courses can be fun, as is a good, hard beach when the tide recedes and creates sand bars and gullies.
This I only do close to dark when there are no people and of course no funerals going on, but I've been known to poke wedge shots in a private corner of a nearby and very large cemetery. By mistake last week I touched a gravestone with my 56, and this is true, the gravestone read "Palmer."
