I live in Indiana, but I'm 10 minutes from the Kentucky border, and 30 minutes from his shop, and he used to race figure 8 cars at my local speedway (and crashed a Viper there like I always say). I'm counting it.
As for actually in state, hands down the guys at DCT Powersports. I've ridden at their off-road park (The Badlands in Attica, IN) for at least 7-8 years, and Aaron Cain and Jerry Beck are really cool guys. Also their trucks are cool and stuff. Y'know.
Jamey Garner is also from Indiana and he's a pretty good driver, never met him though.
I think Joe Nichter also lives in Indiana. Saw him at the Indiana State Fair last year, and he did nothing but stand it on the tailgate every hit he made. I miss awesome wheelies. Now his daughter is taking over, and I think, with seat time, she'll be a pretty good contender. She's definitely eager to drive.
