A place I used to hunt and was a very favorite stand of mine was only 3' off the ground.
Now the explanation. It was on a gas line. There was a small oak right behind a group of elm/pine/fir trees that you couldn't see through. The stand when I was standing on it allowed me to shoot over top the pine trees. When seated it only allowed my head visible. The deer would funnel up the gas line. I was young and I missed a pile of deer from that stand.
