I picked up the same one, not quite sure what I'll use it for but there's a lot of misc options. That looks like it'll work pretty well as long as the middle doesn't sag with wind and weather. Thanks for the ideas.
I was able to tighten it up to get rid of that sag. I was concerned about the same thing. We will see what happens in the rains. I have confidence in it.
We use a similar but smaller tarp a lot during spring bear. Most years it works a as a sun shade, the year it worked as a rain tarp. We spend our days mostly sitting in one spot glassing.
