I haven't hunted deer from a ground blind because I like the vision I get from a tree stand. However, I've had deer come right in and stomp at my turkey decoys inside of 10 yards on a number of occasions when in my Hidden Hunter blind. This spring I had three different deer, including one big old doe, come in. My blind was set up about two hours before the old doe came in, and it was sitting right out in a picked corn field...no brush in at all.
If I ever decide to hunt deer from a pop-up blind, I think I'll just stick a couple of turkey decoys in front of it and watch the fun. The deer never seem to pay a bit of attention to the blind, just the decoys.
