Hey, Glad to know that someone else will experience the wonder that is Indiana. I lived in Indiana for about 14 years, and I hated it. They only have 3 things and they are (in no particular order):
Corn
Basketball
Bibles
The people are real friendly, but shallow, they ask how you are, but that is because they were taught to ask in the name of politeness, but they have no interest in the answer of of becoming your friend. They are just going through the motions.
Also, the sheer number of churches in the state scares me. Here in England, you give directions using landmarks such as pubs and restaurants and suchlike, in Indiana, you go left at the Methodist, right at the Baptist and then left again at the Lutheran. And all the car parks are full every Sunday. Yikes.
Also, all my old friends there, (the few I managed to make) all have an unhealthy love of Dubya and his policies. Its a farming state, so very very conservative. Also, the clocks don't change in the fall and spring like in the rest of the world, because the farmers complain that it is too dark on a morning to work. Damn.
As to the Magic scene, I know that in Indianapolis there is a healthy Vintage environment, and if you look on the Wizards website, you can find a list of stores that hold regular tournaments and Indy is only about 45 mins away from ya'll.
Anyway, don't let scare you too much, I have just gotten bitter about the place.
