Movable bow hunting blind in the shape of a termite hill

I was inside one of those once - worst blind I had ever seen. It was fiberglass, so the thing sounded like a drum any time you bumped the side. It was on a ranch that also used rifles and I think they made it to specs of rifle hunting, but just the material for me was a turn-off. I would take a portable pop-up over one of these any day.
