Rookie, we sank several stake beds on pallets 2 years ago in the pool made of oak and they did produce that year pretty good but last year I went back to the coordinants and they weren't there. I'm thinkin too many anchors being dragged in the pool tore them up or moved them. If you want the cor. I'd be happy to give them to you. Their where 8 stake beds and some pvc beds made but I don't even use the cor. I have anymore.
