I've quite often seen references online about Grayhawk, pertaining to real estate and/or golfing. Heck one time years ago I was golfing at my local course and randomly found a ball-cap on the fairway that said Grayhawk Golf Club on it. Talk about an omen! Anyhoo, on a whim I decided to check out one of these Grayhawk websites. Hmm, not too bad. I could live there, if I had the means of course. Just imagine, if I lived there I could mail everyone I know in the Greyhawk community "Needfest" cards and the return address would say its from Grayhawk! How cool would that be? And I'd have to name my home something Gygaxian, like Castle Grayhawk or Vault of the Mort. No? Well, I can dream!
p.s. Unfortunately Arizona has lousy professional sports teams. Hockey in the desert? I say thee nay!
