Cool Stuff in Indianapolis

[JWKobayashi]

I'm going to be going on a road trip with my wife and a friend of hers to Indianapolis at the end of May (incidentially the same weekend as the Indy 500). My wife and friend have an event to attend at the site of the Indy 500, but I really don't want to go to that.

What other cool stuff is there to do in Indy? Are there any game related sites that I should check out? Game stores?

Thanks for your help!
