This is a blind/stand in a tree.
This was a water tank in a former life.[8D]
This one is across a creek in a little thicket in a cattle field.In is about 10' off the ground.I think someone left some orange in it.
This was a little project my stepdad started to have a place for his grandkids to hunt comfortably out of.It exploded into many blinds,there are many more but I didn't get pictures of them all.
