I fished Old Hickory northeast of Nashville about two weeks ago. I was cuttin out across the lake in the creek channel buoys and looked up and saw a huge rock. Only as I got closer it wasn't a rock. It turned out to be about three foot of the bow of a Carolina Skiff looking boat right out where a big creek arm dumps into the main lake. Old Hickory is alot like Barkley. Be in 20-40 foot of water and then BAM in less than a foot of water just barely outside the buoys.
