I've been thinking of sinking a few x-mas trees left over. What do you guys think ?

Natural Christmas trees--not artificial trees--make excellent crappie attractors.

Insert the trunk end of the tree into a 5-gallon bucket filled 3/4 of the way with concrete. After the concrete hardens, place the tree in an area of water that does not have an abundance of cover. Alternatively, attach the tree to a concrete block and then sink it.
its got to work if you thnk about it .....input welcomed
