I hunt in a ground blind all the time an no i have not tried that. To your point, if you left it out there long enough it might be OK. I know of a few places around here that people have built large elevated box blinds and placed them in the middle of fields and have very good success.
The blind would have to be left out for a long time and would have to be of a quality that could stand to be out in the sun and conditions that long
