I actually wrote a post last week on things to do in Massachusetts. You can check out the link for information.

These seem more central though and the chances are that since you are from the area you may already have been to these places. Also if you look at the section of the website on
things to do in Massachusetts you'll find places of interest listed down the left hand side of the page.
Other suggestions are Cape Cod Seal Tours, Trek with Llamas in Pinetum Farm, visit the Wolves in Wolf Hollow, Dr. Seuss National Memorial, the Red Jacket Beach Resort, the ecotarium Worcester and Whip City Speedway.
I hope this was helpful
