We've got two indoor ranges here in Louisville. Bluegrass, as you mentioned, is right off the Watterson Expressway (Newburg Rd. exit). It's ok to shoot at -- though I don't like the ventilation system in the range area and therefore don't make it a habit to shoot there. I know, it's just a strange habit I have not breathing in all of that lead! The other indoor range is east of Louisville in Crestwood. Open Range is the nicest range around -- but it is also more expensive than Bluegrass. I'm a member at Open Range and shoot there on a regular basis. With the weather we've recently had, I'll assume you likely won't want to shoot outdoors! If you're interested, there is a large gun show at the State Fairgrounds this weekend. Enjoy your time in Louisville!
