Hi,
Some out of Boston trip options:
- Boston to Kennebunkport, ME.
- Salem and go on a ghost tour.
This area, an hour's drive, is scenic, historic and quite worthwhile visiting, and a chance from Boston.
- Rhode Island - worthwhile, but is a non-scenic drive.
I'd recommend the drive to Kennebunkport, with tea once you arrive. As the earlier poster mentioned, get in some shopping on your way back.
- Cape Cod - pleasant, but not scenic until you get there; Provincetown is unique

.
Cheers
Ben
