Oh, and for those who suggest that large, world-wide tournaments are a possibility, look at the limited success that Smeagollum is having trying to get something going in May (>8 participants)* and Hawkeye got zero interest at GenCon (nerd central...you would think a few people would want to show).
Either way, if you host your "Worlds" in the Washington DC Metropolitan area, I'll show (Movie Block only), but otherwise, find me on GCCG because I'm not going to travel to Zaire to play cards.

Edit: * Smeagollum: That's not to say I want your event to fail. I actually want a lot of people to show up and then they can come to the site and play on GCCG and I have competition there!
