I figured if they make good fence posts they'll make good crappie structure. Most of them are about 4' long. I've built 2 condos so far... waiting for the crete to dry... these will be the first I've ever set out. I've taken a post and set it vertically in a five gallon bucket of concrete. Then I've drilled holes (2" diameter) into 4 foot long oak logs which are about 4" diameter and stacked the logs onto the cedar post criss-crossing every which a ways horizontal to the ground. Basically, it's the simple ernest paty design with PVC and rebar but with wood. I got more wood than pvc so I figure I'll use what I have. They are much heavier than pvc and harder to sink, but seems like many of yall believe wood/natural stuff attracts better anyway. Guess I'll have to get these and more in the water and see...
