bdGreen, not sure re: the dates of your travels (maybe you are already there?) but suggest you avoid the I-95 corridor as much as possible. Heck, I avoid the I-81 corridor, too, as that is nearly as miserable.
If you can avoid both reasonably, go for other options. In fact, entering MA via I-80 to I-90 near Albany/Chicopee is my preferred route.
Once there do visit downtown Beantown. Lots of cool restaurants and bars. Avoid any chains...many better choices...you'll see. Nary a straight street in Boston...map is most useful. Visit the Navy Yard...part of Boston NHP. Easy walk from the downtown area. The USS Constitution is berthed there. It remains on active duty...yes, it does.
Faneuil Hall is a building adjoining Quincy Market. Bostonians formerly referred to each, separately. Now just about everyone calls it the Faneuil Hall Marketplace; I refuse.
Eat there! Grab a lobster and/or clam roll. Eat a big lobster. Find a Kelly's Roast Beef store. Eat there!
Drive down to the Cape if you possibly have time. Simply perfect this time of year. Drive out to Provincetown and you can watch the sun
SET on the Atlantic Ocean. Yes, you can.
No worries re: LEOSA if you are covered. I visit Boston often...never an issue.
Check out Fenway Park. You will be shocked when you see it's a dump. Visit Southie...some "interesting" folks there but rapidly becoming gentrified. Some residents still view Whitey Bulger as a hero.
Find a beerroom that serves Narraganset. You will like it. Wish I could remember its name but there is a tavern just a few steps away from Faneuil Hall that serves 24 ounce Bud Lights cans for $2.00. Hard to leave there!
Boston is cool...and oh, so cold.

Bet you will buy a hat and gloves if you spend any amount of time outdoors and didn't bring them. Coldest place I have ever lived and windy, too. By actual weather stats windier than Chicago.
Enjoy your travels.
Be safe.
