I would place a ground blind near something that breaks it up a bit but is at the edge or in the open.
You did not say but I am assuming that you bow hunt judging by how close your existing stands are to trails. If you gun hunt, move back with your ground blind. 100 yards is still a reasonable shot with a smooth bore slug gun. Set up 50 to 70 yards from where you think the deer will be.
I gun hunt and use just a stool in some light cover. My spots are things like an isolated cedars or weed patches at least 50 yards from where I expect the deer to travel. The ideal spot give shots in more than one direction. I pick the exact location based on the day's wind direction.
