This project does three things: 1) anchors the canopy yet it can be moved, 2) adds shock absorption to help it handle wind gusts better, and 3) lifts it higher to enable use by a taller vehicle. NOTES: This lasted for several years and survived some pretty hard winds, but not snow! I put clothes line quality rope in an X pattern from the top of the back posts to the bottom of the middle posts and visa versa to add rigidity. I also put similar line with a clip, for quick removal, from the tops of the back and front poles to the spare tier rack or bumper for similar rigidity side to side. I did not find the shock absorption bungies were that much help. The cinder blocks seemed to be enough weight when wind tried to make a sail of the canopy, but they could be dragged. I drilled small holes in the concrete driveway, dropped in a big nail, then set the blocks back over the nail sticking up into the bottom of the PVC pipes coming through the blocks which kept the blocks from being dragged. After 3 tarps rotted out in the sun over the last years, I have now given up and installed a metal roof car port!
