It sounds like they just want to keep it a "Good Ole Boy's-n-Girl's type network, their own private secret society.
It has been said as much. I understand the secrecy, places get burnt down if word gets around. The wrong people can get to know where they are.
I am not parley to any of the great ones as I'm not part of their community. That's OK, I'm happy with the wrecks I find.
