There are plenty out there. I live by the highway in Brattleboro and see them all the time in a field up the street in back of the country club. I see a lot in the forests and fields going up the hill around the edges of town. It's true the forest is thicker but there are also more people everywhere with big patches cleared around them with plenty of feed. So they all hang out in the edges of the forest around the valleys where nobody shoots at them because it's to close to houses and often against town ordinances. Mass. has a huge deer population because of this trend. I suppose that's where the ones we are missing are. Up in the mountains and the larger swatch of forested land in the Green Mountain national forest areas it's hard to catch site of them at all.
It's really frustrating because everything is heavily posted in the areas where the deer are the public lands and places where you can hunt end up with 3 or 4 times more hunters than deer in Nov.
