About an hour from Boston, not far south of the New Hampshire border, is a no-frills pick-your own apple orchard with hills, thrills, and hundreds of trees full of fruit. It's called Autumn Hills Orchard , in the town of Groton. This is not a place for anything but fruit. You cannot, at least as of this writing, buy cider, donuts, kettle corn, or maple candy. There is no hay ride or corn maze. If the weather is bad, call first because they just might close up early.
