The question should have been, may I legally walk onto an executive course and play? However, can I walk onto an executive course and play?, I would answer yes. I actually did that at Southern Star executive in 2011. I hadn't only moved here a couple of weeks earlier, I hadn't even played a round of golf yet. My neighbor said he had never played golf. I had just gotten my cart, so I told him jump in. We drove to Southern Star, which is about 200 yards from our vllla. We played holes 3, 4, 5, 6, 7 and 8 and then left. I never saw a marshall, in fact I never saw another player. When we got back I went online and discovered that Southern Star was closed. This is a true story, the rights are for sale.
