There aren't too many that are "close", but the closest ones are Blackhawk Farms, Autobahn Country Club, Gateway, Iowa Speedway, Heartland Park, Putnam Park, Grattan, Road America, Brainerd, Mid America Motorplex, Hastings... and that's pretty much all I can think of in a ~10 hour radius of you/me.
For the track you'll need a helmet (obviously), full gauntlet gloves, suit (I recommend a one-piece), a back protector is highly recommended, and riding boots. Get comfortable on the bike so things like panic braking are a natural instinct. You don't wanna be mixing up the brake lever and the clutch lever on the track.
