RE: Ground blind seat
For the last 2 years I have hunted out of the pop up ground blinds. A seat was always the problem. I tried the bag chairs and they were comfortable, but I couldn't move freely in them to shoot from every side of the blind. Then I tried a 5 gallon bucket turned upside down and that wasn't comfortable. I am rather tall so I used 2 stacked 5 gallon buckets with a swivel top on the top bucket.
This year I made a portable wooden blind and for a seat, I also made a 40 inch long bench to sit on. This way I can move back/forth on the bench and not make noise and I made it the right height to be comfortable sitting.
In my portable blinds I also place a shooting rest at each window.....that rest is an old realtor "House For Sale" frame. It's perfect. You can sink it in the ground, and place your gun on top of it as a gun rest!
