It's a 4 hour drive to the Pennyroyal quarry in Hopkinsville, Ky. and about 3.5 hours to the Madison quarry in Alabama. Not sure if there are any closer to you. I've been to Pennyroyal but not Madison. It's 8 hours to Panama City which kills a day each way, but a 3.5 - 4 hour drive could put you in the water on a weekend instead of waiting for vacation time.We all love it, but living in the Memphis area provides no diving opportunities
