I see your in White House. You can get them at Academy and K-Mart or order online.
Percy seems to be doing well. Barkley was on fire for crappie last week, KY seems to be rockin too for them so I would imagine Cheatham and Old Hickory will be next for the bigger ones. The bigger ones are showing up in my smaller shallower lakes right now too. It won't be long for every where. Dogwoods bloomin?
If you are going to be on Old Hickory or anywhere for that matter don't over look one key area. There are tons on boat houses/docks. A whole bunch of them have things sunk off the ends or sides. When I crappie fish and see a chair, rod holder or lights on the end of a boat house/dock then I am fishing it.
