The best indoor range I've ever been to was down in Jacksonville, NC. It was clean and well lit, rarely crowded. You paid $10 or $12 and you could shoot all day. They pretty much just left you alone, and let you do draw drills. Fantastic place, I used to go a lot. I'd like to find a good one around Indy - or just open land to shoot on, though that's less exciting in Dec - Feb.
