Is there any other little city that hits above it's weight like Lexington when it comes to strip clubs? It's only the 109th ranked metro in the US but for me it's one of the best strip club cities I've been to. You got some good talent and mileage available.
Any theories as to why? Cincinatti is slacking? I don't know much about the horse industry but I assume you got some high rollers from that + University of Kentucky girls throw in some strip club friendly laws, you get a good place for strip clubs. Most places are bad so on the off chance you get a good one, I think it's worth noting. Probably one of the more underrated spots on here you don't hear about as much.
I love Lexington and Louisville for the same reasons you mentioned. The big difference is Lexington allows the girls to go naked on the stage where Louisville forbids it by law. Of course Louisville also forbids extras but just like the ban on nudity I've found most girls are willing to overlook the law for a reasonable tip. Your money goes further in Louisville but the talent level is a little better in Lexington.
They are kind of an oddity since the area south of them (Tennessee) and the area north of them (Cincinnati) are both terrible strip club areas. Tennessee at least has clubs with good looking girls, just no mileage. Cincinnati has neither good looking dancers or mileage.
The reason you don't hear about Kentucky strip clubs more is that most people don't have any reason to go to Kentucky and aren't willing to go just for the clubs. The clubs are good, but unless you're already within a few hours drive they aren't vacation destination level good.
