If you take a look at the last picture you can see that all 8 legs are anchored by a 50# cinder block. The plastic would tear away first. I've had a couple of 'blow outs'. But usually the wind comes in one side & blows the back corner loose. It's never come off. But I use a lot of zip-ties.

P.S. Boy you guy's are a tough crowd, 2400 views & I haven't even picked-up 1 star!
OK, I guess I'll have to try a little harder!
