I'm almost positive they could charge a fee to play. I'm pretty sure they charge a fee in St. Louis. I've heard they even have a concession stand at the entrance so you can purchase beverages, snacks, etc. I know it has been a topic of discussion lately as far as pay to play courses are concerned. But I really do think that if you build it, they will come. Cave golf is so unique that I'm almost positive people would come ready to pay and play. How has it fared in STL? Jamie seems to keep track of STL golf quite a bit, can you comment?
