Thanks for all your help Scott!
A few more details...
I wired 2 hog panels together in a circle and then drove the posts. Used two panels for the roof. Cut down some of the section in the back where the door is and in front where my shooting windows are. I used the Cabelas XL ground blinds (179.99 each). I had about $250.00 total cost in each one.
Also recommend you use dead cedar trees if possible to brush it in so the color stays the same and the amount of cover as well. Cut the branches off as long and whole as possible and stand them up like trees wired or zip tied to the hog panels.
