[Fot] Securing an EZup.

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.

Most EZups are a disaster waiting to happen in a wind of more than 8-10 mph. A 15-20 mph gust will have you chasing it down the paddock unless well secured. A 12 mile per hour wind will generate 86lbs of force/sq.Ft. x the area of the covering. So a 12x12 EZup. could generate up to 1032 lbs of force.
Just securing it with 25 lb weights is unworthy of the pressure created by the wind.( If you are a sailor, you know what a little gust can do.) As mentioned in previous posts, start with 5 gallon water buckets (8.3 lbs/gallon) at each corner, and tie it taunt to the upper frame of the EZup. Helps if you know your proper knots. This helps transfer the wind force to the ground. Just weighting the foot is inefficient because much of the force is wasted just holding down the ground. Gravity has that covered.
The next step is to secure topside belly lines over the EZup. Use separate buckets, (or alternative tie off ) and place them at the corners. Toss lines diagonally over the top and secure them tight. This will reduce the billowing effect of the wind and the pressure. You can also tie to a car or?? but it really gets displeasing and embarrassingly hilarious when someone makes the beer run with the EZup in tow.
