My sister and nephew are coming out to stay with us this month to look at engineering schools. My nephew loves anything transportation related - planes, trains, automobiles, etc.

We are definitely going to take the commuter rail into Boston and ride the T. I was wondering if you might have suggestions for other things to do - either museums, exhibits, or activities that would fit his interests. Open to locations, but probably won't want to drive more than a couple of hours in any direction.

I had thought about taking a water taxi, taking Acela to Providence, duck boat, Boston Fire Museum, but I am guessing there are more obscure places or things to do that would be cool.

Thanks!
