Just used mine yesterday. I also have another for a spare. The one I used is getting pretty beat up but still useable. As far as keeping it from being blown away I use a small old runner sled. I have a tote box with lid mounted on the sled for my seat. With the sled inside straddling the ribbing it will not go anywhere short of hurricane force winds with my heavy butt sitting in there. LOL. To bad they are no longer made.
