I made this blind out of sheets of 1 5/8th inch structural foam with 1/16th sheets of a thermoplastic laminated to both sides. It is rigid enough to walk on supported 4 foot apart. The blind has removable Lexan windows. A 4 by 10 foot piece of this material weighs less than a 4 by 8 piece of 1/4 inch plywood. The whole thing is designed to bolt together quickly in the field although I may decide to permanently mount it to a small trailer that Mr Goat call pull to wherever I want it. My small propane heater should be able to keep it comfortable even with the front window open.
