Montauk Downs is too low. A lot of courses that deserve to be on that list - Hominy Hill, Breckenridge, Greystone (Baltimore, MD) - are absent. I'd also include McCoullough's Emerald Links (despite its kitcshiness), Also, isn't there supposed to be a steller municipal in Texas? And there are tons of great Ross municipals littering the southeast US, but I'll let others who know that bring those up.
An interesting idea, but I doubt its a solid start just yet.
