The other day New Hampshire changed is reciprocity with Maine. This means if you have a Maine Concealed Carry Permit you may now carry in New Hampshire. All of their local laws apply, and you are responsible for knowing the laws. If you are carrying without permit in Maine then your SOL. Chalk up another win for Maine and another point to get training.
