Hi:
Where at in KY? I'm in Hopkinsville, in the southwestern part, and we've got Pennyroyal Blue Springs Resort (with an onsite dive shop), a nice quarry where a lot of dive training takes place. You've likely heard of it and dove there, but thought I'd mention it just in case.
If you haven't run across them yet, there's a Facebook group called the
Kentucky Piranha Patrol (Bluegill are the 'piranha' in question, from what I understand). Again, you may already know them. I don't post on the page much, but once in a awhile.
Clarksville, TN and Nashville both have scuba shops & interest; Clarksville has Water Dogs and My Dive Time.
Richard.
