Wind even if only a short microburst can be devastating. Not the same situation but we used to set up at trades days and car shows, always wanted to have a tent over our display booth, at one such show the rules were no anchors driven or screwed into the ground, if you requested to anchor a 20x20 or larger tent they would provide up to 12 55-gallon drums filled with concrete, 3 drums at each corner for a fee. It was always a good idea to pay the fee and take them up on their offer but many would decline the extra expense especially for the smaller tents. One year a microburst passed through and destroyed 100's if not possibly a 1000 tents, we wound up with close to 30 tents wrapped and twisted around our booth what a mess
