I hunt in Cumberland/Yarmouth and also in Biddeford for deer, and most of the time I am deerhunting in/around oak trees. Whenever I'm out deerhunting theses oaks theres always squirrels around me. The pine trees are where I always see more red squirrels and chipmunks than gray squirrels. I would try finding where a stand of pines/evergreens meets an oak patch and just sit down with some snacks and wait.
