There's a great one in Austin that starts with a V. When I remember it I'll edit this post and fill it in properly. The International Game Designers Association should have some useful information:
IGDA - International Game Developers Association
Depending on what part of game design you want to get into, you could go into graphic design or computer engineering at a normal college if you have to. Keep in mind most game design colleges count as technical schools and thus you don't actually get a college diploma. I too have interest in game design, but I'm going for a creative writing/visual arts double major at a liberal arts school.
