Jim,
in early June, Joe (an awesome amateur agility photographer) was setting up an umbrella on a sunny day ... I was so impressed with his homemade system I tried to get him to make me one that was on a Sat
on the Sun it poured, he decided not to shoot, so I "borrowed" his setup & returned it in two weeks ... he hand build himself version 2, and sold me v1 for cost of materials
so, now I have a sturdy shade/shelter regardless of weather or wind ... love it, keeps me & my gear out of the sun or the rain LOL
