A few years back I attended a seminar given by Dr. Ken Nordberg, a noted whitetail biologist. He feels that Deer have learned to look up, as deer hunting from elevated stands has become the normal in the last half decade. He said that his hunting success has gone up since he started hunting from the ground again, from pop-up blinds and brushed-in blinds. I currently guide in North Texas, here we hunt from ground blinds a lot. I like the versatility of a GOOD pop-up ground blind, can hunt any wind, wooded area as well as wide open fields. There is a time and place for each type, elevated or ground. The ground blinds are a lot safer.
