Well i would set up the ground blind where you can use natural cover as well. And DONT set it up directly infront of the entrance point. That would be like a wall to them, not to mention if you get spotted in it or shoot one out of it they will be on to you from then on. I would put it to the side of the trail, 20 or 30 yards off, depending on how comfortable you are shooting. Put nature cover around it, and try to place it in a spot that will not directly effect deer traffic. If you do that you should be able to have a good spot for the rest of the season.
