Minnesota deer stand building

I am always researched new ideas for deer stands from salvaged materials, and this blind, from a Kentucky discussion forum, represents true ingenuity.   I may have to copy the design, minus the ground poles, as I build my stands up in the trees, and for Northern Minnesota, I would add in some pink foam-board insulation, and some salvaged, sliding windows.  I have a few stands already, but I due to the extreme cold temperatures the last few seasons during deer hunting, I feel like having nice warm stands, at least for breaking the winds, has kept me put longer, and also results in meat for the freezer.
