Bank fishing around Nashville 4/28

May need to repost this in the Middle TN Crappie Club Forum....
I will be in the Dixon/Nunnelly area 4/27, heading back to Knoxville 4/28, I wanted to stop and fish somewhere Monday morning on the way back through. I have been doing really well fishing the riprap below Ft. Loudon here lately, is there a dam in or around Nashville that would be good to try? I looked on Google Earth at J. Percy Priest and Old Hickory. Also what about a bait shop to get some minnows? Thank you for any ideas.
