Traveling in the Northeast is tricky. Stay out of MA, NJ, NY and MD. Understand that each state has very restrictive and very different laws. In NY, possession of a magazine holding more than 10 rounds of ammo manufactured after 1994 is illegal and they often do not honor federal transport laws. NJ and MA both have ammunition restrictions against hollow points and other types as well as firearm transport and capacity restrictions. MD is a restrictive state as well. The fact is, you need to research the laws in every state you travel through for yourself. Do not rely on websites other than state statute research, my info or anyone else. Get caught with a 16 round mag of hollow points in NJ, locked up or not, and you'll have a new zip code and a new roommate for a while. Read the statutes and bring copies of them and the FOPA with you. Teaching the law politely with proper documentation may save you an uncomfortable ride and stay in a police hotel. Good luck.
