I wish I could remember where this was. We were driving back to New York City from Quebec City on what we liked to call a "dot" road. The maps we had — frayed, wrinkled and folded incorrectly dozens of times — had a line of dots running parallel to scenic roads. These roads were , narrower, curvier and above all, slower than highways, but we were young and had time. We drove on lots of them.
I remember that it was a North South road and I think it might have been just on the New Hampshire side of the border with Maine. There was a sign for a parking area and a hiking trail. We spent maybe a half-hour there.
