I live in Louisville and race at Newcastle, IN.
The track is a little over 2 hours away, it’s sprint asphalt. Awesome organization, one of the nicest tracks in the country. They also have a few classes that would be great if you’re just starting out. Clone is the most affordable way to get started and Newcastle usually has 20+ entries and two classes you can race in. Tons of people in Yamaha if you want to go a little faster, and they also have a Novice TAG class if you want to go really fast (also close to 20 entries per event).
