I don't know about State but the National Events bring in out of towners who need shelter, food, entertainment and transportation. For instance, I'd bring three to such a tournament. That meant plane, hotel or on site shelter like a condo, breakfast and dinners et al. Tickets for the course club house. We did this Friday through Sunday I wasn't the only one there that did this. So the "local" community does get a surge to their economy.
You are correct that locals do exactly what you have written. That's because it's a local held event but locals are not the only one in attendence.
I just read how you seemed to put going down and inquired why you bothered to go to two.
