I ran Charlie the Feist over about 65 acres on my place day before yesterday and never found even a red squirrel, and we both hunted hard. 21 years ago, when we bought this farm, Patty and I walked the whole 120 acres this time of year.. The creek bottom on the south 40 was alive with snowshoes. That and the deer herd were major factors in our buying the place. I've never seen them like that since, and I've shot very few of them, so it isn't overhunting.
