Not talking clubhouse, but actually on the course. What is the weirdest of most unique feature you recall existing?
For me I was playing in the Philippines and they added an electric fence to one of the holes to keep the monkeys out of the course as they would come onto the fairway and steal your ball after hitting it. One of our caddies, which were all ladies, went out onto the edge of the fairway before we hit as well.
I didn't see any monkeys actually, but after I hit I saw a couple 8-9 year old's run onto the course and pick up my playing partners ball. The caddie tried to chase them but oh well this is what they meant about monkeys I guess. They entered the course from another location apparently as I didn't test the electric fence needless to say.
A friend from Texas said he played a course that had an old junk car in the middle of the fairway for years. Not sure where that was, but I guess it was a poor mans tree that didn't need water or maintenance.
