"like a fox"
targeting Crappie in a river environment means looking for anything that blocks current. Bridge pilons, stumps, downed trees, wing dams, duck blinds, and even eddy water areas can hold Crappie. They will be in the lee of the cover ... in the slack water/eddy water produced by the cover slowing the current. And any creek or offshoot of the river, that has a couple of feet of water, could be worth a look. Those "logjams" are certainly worth dropping a jig around. ........ luck2ya ....... cp
