Liberty holds some decent Crappie, or at least it used to. Somebody put me onto the Nicodemus Rd. Bridge a few years back as a good spot for Crappie. I've tried it several times since w/o a lot of luck.Other than that, I don't fish Liberty enough to know the water.
You might want to try Black Hill at Boyds.
You have a fish finder on board? Sure beats fishing blind.
