I've spent a lot of time in NH and VT over the years. I've worked in NH some years back for an extended period in the Manchester area and saw people carrying every day. In restaurants, in supermarkets, on the street, everywhere! It's a non-issue in this part of the country. MA has no concealed carry laws, just a legal right to carry a firearm, period. You don't see it very often but people do on occasion carry openly. My daughter even has a regular customer at her bank that carries a 1911 once in a while. If it can be done in the Northeast, it can be done anywhere!
Personally, I won't in my neighborhood. Not that my neighbors would mind, it's just that I feel more comfortable not being conspicuous and find no reason to bother to explain myself. The local PD aren't the problem, the problem is the brainwashed frightened masses!
