I received this photo from John Maner with a nice 6.3 pound largemouth he caught on an Alabama Rig on a Tennessee River lake. Nice fish John looks like you had a great day on the lake. I met John at the local Gander Mountain in Florence, Alabama recently we discussed lures and techniques about the local fishing conditions.
