We managed a CG out west once in a area that is famous for quick and violent thunder storms. There were several tenting sites on the west side of the CG. As the storm was approaching and the wind began to blow, I saw a tent come blowing across the yard, sort of rolling. The owner was obviously gone. I grabbed it and took it back to where it came from and when I set it back, it started again. Grabbed it a second time and thought I might have to sit with it. It occurred to me that rocks don't get blown around so I put two head size stones inside the tent that anchored it firmly. Never heard from the tenter but I wonder what he thought when he opened the flap and saw the stones lying there.
