We did a show last Spring, and we lost two tents before we finally gave up. We sold two spas though!
The first tent came down in between the rows of spas and didn't hit a single one. Tent was totaled, but the tubs were fine. Second tent started to blow away but we moved a truck in close, tied one corner off to the bumper, and then began to strip the wall panels. Once we had the walls off all the way around, it wasn't so dangerous. Of course, by that time all of our brochures, silk plants, lighting, patio furniture, closing areas and paperwork were somewhere out to sea.
