I once saw a photo of a tractor trailer race rig canopy that had been =
tied down to golf carts with ratchet straps at each post. There was a =
wind/rain storm and the entire canopy, 3-4 golf carts included, flipped =
over the top of the trailer and the carts were hanging by the straps on =
the other side.
My takeaway is that in the event of a big wind, take down the canopy. =
Nothing will secure it in a really big blow.
