We have had a few big winds here that tipped things over. We have since gotten a lot smarter about setting corners together to brace them. We will often set them up in "T" shaped or other configurations to brace against wind. Some of the fancier ones I have seen advertised have the boards set in brackets, rather than nailed on. I think these would be quick to stand up. The other option, which is what we plan to do for corrals going forward is to drive a big post and chain the panels to the post and each other.
