I am looking for a 10x10 Canopy to park by VW Convertible under, and I live less than a mile from the Pacific Ocean. So far, I have purchased so far 3 of the 10x10 pop up shelter with the little stakes that go in the ground, but because the tops are not vented, when we get the winds that can come up from the Ocean, the wind gets under it, and picks it up and then it gets destroyed. Does anyone made one where the top is vented, so the wind won't pick it up and carry it away?
