"Anything of this size is bound to bring in someone who believe they are above the rules and will do what they please"
That's one of my issues with the 500 x $500 senario. There is definately power in numbers financially but there is also power for abuse.
"If it is more than 2 hours away, just a work weekend would have substantial investment for me"
That's another issue. A centrally located east/west site in NC would be the Mocksville area and that is still a 4 hour drive from Murphy and Jacksonville! Definately not going to be able to please all investors with ANY site selection and the overwhellming majority right now are "Depends On Location" votes.
