Have you done any ground stands with natural materials? Just a little plastic can make them rain proof and they are not noticeable like a pre-made tent, cost about a sheet of plastic. I'll get a picture of one close by. Make a few for different weather/winds.
I've also done pit blinds, not good in inclement weather, and field of view limited. But did it bow hunting right next to a run. Pop up and deer are like WTF? You are 6 yards away?
