Burn the Christmas trees, and forget you ever thought about sinking them! Three things to know about sinking brush if you want to eat crappie? Willow, Willow,Willow ! Wait until the leaves are on the willow trees, thin get your chain saw , some cinder blocks, a little galvanized wire( barbed wire is what I use because I have it, not because it's best),some plastic jugs(if desired?), about $4.30 is your financial exposure per set! And go to work,yes that's right , you have to work before you eat ! In a half a day you can have five good crappie holes out and ready for action, take 8 fish off each one of them and you and your buddy just limited out! I have caught fish within two day of putting out willows,it's quick and easy, most of all productive. With minimal loss of jigs and a more comfortable environment for you fish. Hope it helps!
