I am most interested in seeing how they weather the wind generated current through the winter that historically has flattened my other piles. With the eight bottom pipes spayed out in all directions all it could do would be to roll on another eight. Not shown in the picture is the one pipe that goes straight down in the center...I'm holding it in my hand. It is the one piece of pipe that has to be cut shorter than the others. That is the pipe that you slide through a few bricks and then glue on a tee to keep them on. We lost much fewer hooks this year too
