Massachusetts isn't as bad as some people think. . .IF. . .you happen to live in a town where the chief of police is pro gun. Some towns give them out left and right, others not a chance. I don't believe Massachusetts has reciprocity with NH, Maine, or VT so if you visit Boston plan on leaving your firearm at home.
That being said, just because MA isn't as bad as some people think don't get the idea that we are firearm friendly. If gun laws are a major factor for moving into the region then you probably don't want to come here.
Feel free to ask any further questions.
