Our favorite small town in NE is Rockport Mass. Very picturesque. Pictures of it are often found on jigsaw puzzles and promotional ads, etc. The best part is the fabulous clam chowder that you can eat right on the docks, where the fishing boats come in. It is the most delicious NE clam chowder!
Cape Cod, Acadia National Park, and the city of Boston are also beautiful areas to see. Just driving through the NE countryside anywhere is fantastic!
