I have shot dozens of deer in Iowa, all from the ground. Most important thing I look for is the proper cover and preferably somewhere that no one would want to put a tree stand. Most of the time it is the in the edge of one of our cedar clumps. Our Iowa versions are not really cedars like one would see out west, they are closer to junipers. They grow in tight clumps at times, but deer like to bed in and around them. More than half of my deer have been shot using them like a blind. I simply cut my way in and take the cuttings and stick them in the ground in front. On state land it is not legal to damage trees, but quite often there is no need because the DNR has been cutting them down on our hill sides as they are considered to be an invasive species on our prairie hills.
My other trick is to make my self as comfortable as possible, Huntmore chair. The set up works just as well for turkeys.
