Yesterday a crazy dust storm passed by, visibility was maybe a couple hundred feet. I rushed home from work to find this.
Normally, this is how the shade canopies look.
I even "reinforced" the base of the structure with several of these iron U-hooks driven into the ground, but I guess the hooks are too short, and the wind was too strong.
A few of my shade canopies had their 4 posts buried about 18" in the ground, like this one around a White Sapote, those were not blown over.
I guess I will have to disassemble all tha canopies that I've built and start from scratch, and this time bury the supporting posts in the ground.
