It sounds like the Corydon exit is your best bet, but if you do head up 65 North, I wouldn't go all the way to Seymour. Exit onto Highway 250 at Uniontown; there's a Lion's Den **** store there (I know this because of the controversy that has surrounded it since Day 1, not because I'm a frequent customer or anything). Turn left and you'll follow 250 all the way to the race track. I hate going through Seymour to Brownstown from the south. There's also plenty of restaurants before getting to Seymour.
