This is a picture of my 4X4 stand I put up 4 years ago. 14 feet up and features windows that close for non hunting storage. Piece of carpet, heater, and office chair make the hours sitting in it much easier.
I have 4 earth anchors and cables too, but I can't seem to keep them tight in my soft soil. May need to make some concrete pads for the cables and turnbuckles.
