Reason #054 to come to Washington: Street art. I think it speaks for itself.
Reason #053 to come to Indiana: The Arcola Tractor Pulls. Every July the barely-a-town of Arcola becomes over populated with America's finest to witness one of the classiest sports around--tractor pulling. Bonus: I live right next door so we can't sleep for a whole weekend. I've trespassed many a time to take photos in the tractor pulls during its off season.
