I live in So. iN, near Louisville. I have been to the KY Gun and Military show in Louisville several times. While it's always fun to walk around and browse, I can't buy handguns because I'm not a KY resident. I'm mostly interested in used guns and was thinking of a road trip to the Indy 1500. Is it worth the trip? Are guns bought there private party sale or more like a retail sale wrt paperwork?
