As I get older my body doesn't work the way it used to so I'm preparing for when I cant climb trees anymore. I placed blinds like this strategically throughout my property with very little expense. As you noticed probably, I added a rubber roof to each one also to keep the elements out.
Not sure that it is ingenious or that I'm proud of stealing it from a Christmas decoration design in downtown Chicago a number of years ago. My wife talked me into taking the 3 hour trip to see what downtown Chicago looked like in the winter. On our way home she asked me how I liked it and I said the take away message was a new way to make a deer blind. SHE JUST ROLLED HER EYES. LOL
