I had an easy duty: to keep everything devoid of water. My family lives in rainy Seattle, Washington, where a gap anywhere will penetrated by flowing rains. That's why us dwellers in rain could use all the help we can get when it comes to protecting our valuables from storms. Personally, I have a car, a go-cart, and an ATV sitting next to my home with no protection. To preserve them I purchased specially designed fabric Dodge Durango truck seat covers to stop moisture from ruining my stuff.
These tarps do a wonderful job at keeping moisture out, and they are more affordable than building an overhang. Too bad all those toys can't fit below my patio enclosure. They even feature snap buttons to ensure long-term durability.
I'm glad my stuff has a way to stand the deluges. I just wish there was something for me.
