Lots of old school Irish pride in Mass which is where some of that subtle ingrained racism seems to stem from, especially in places like Southie and other outlying Boston areas.
Weather: Humid in the Summer, cold and miserable in the Winter. Beautiful in the Spring and at its best in the Fall (between the end of August and end of October). That smell of burning wood, cold crisp air all around you and hearing the leaves rustling against each other... nothing like it.
Landscape: Lots of damn hills
Things to see and do: Lots of historical places (as you said you had interest in, Himu), if you live near Boston there's great nightlife (as long as you avoid the fuck heads), lots and lots of places to eat in Boston (especially Seafood and Italian). Boston isn't as complex or accessible as New York as far as public transit but they have a system in place inside of Boston that gets you in the general area of where you want to be. This makes it fun to just hang out in Boston and take it in. On the flip driving IN Boston fucking sucks so hard. Its like the place retained the roads made for horse drawn carriages and its like a maze at times.
Other stuff: If you do come here, you'll want to try and visit Vermont and Maine too (either, or). Its nice in Mass but the land is stunning up there. Its about a 3 hour drive.
