Can you guys explain the deer yards to me? I am a little confused on why they travel so far. When I was in Maine in 95 and 98, I thought I remember seeing many softwoods swamps, maybe a few acres each, that would support deer during heavy snow. How big in acres does an area have to be to hold the deer? I read a post saying that some deer travel 40-50 miles to yard. Are they not passing through any softwood swamps during their travels? It seems as though the deer are sitting ducks, especially if the deep snow freezes on top and the yotes can walk on top of it. Someone please fill me in.
