Well I picked up a Rockin 2 Metalworks quad pod (Mike is a great guy and builds an awesome product). I didn't have the money to get a nice tower box blind so I figured I could make something pretty awesome out of this. I work in the boating industry so I had our canvas shop do some modifications for it. I added a custom made bimini top, removable carpet, sunbrella canvas that wraps around it with a zipper door, canvas that zips from the bimini to the frame on 3 sides with windows. I think it turned out great and I have hunted it a few times and it is very sturdy and comfortable. It blocks out the north wind and keeps the rain off.
Here it is naked
Here is me putting the canvas up
Here it is in its final state
Here is a view from 100yds out. The feeder pin is 220yds out but the pasture is big and deer just feed all over it.
