I think that there are a lot of variables to take into consideration in terms of hunters to acreage ratio. My 19 acres is entirely wooded (with lots of underbrush in some spots) and hilly. I have two stand sites at opposite corners of the property and its not a problem at all for shotgun season even when much of the cover is gone. I could easily put in a 3rd stand during early bow season when the brush is thick and 100 yards seems like a long walk.
