this site. Be aware that in many states the law varies from one city/county to the next. It can vary, somewhatl within a single jurisdiction. And enforcement can vary from one cop to another, down the road.
I have found it helpful to call the main office of the state police agency for helpful information, prior to any trip. All but one have been courteous and forthcoming. Some will even warn about local jurisdictions, with varying laws/ordinances.
Plan ahead as you go. That is, examine the law/rules where you plan to be tomorrow and next week. You will need to avoid some states in order to keep your sanity, and perhaps your freedom.
New York, your state, is one of the examples of a difficult state to travel while following the rules. Massachusets is impossible. Idaho is simple. In Idaho, where I live, you may carry as many guns as you wish, any way you wish except:
If you are in an incorporated city, a mining or logging camp, you must have a concealed carry permit to carry concealed. The permit can be from anywhere. Your New York permit will work just fine. You may carry a pistol on your hip or a rifle, slung on your shoulder, almost anyplace you wish to go. (open carry.) You can't carry a firearm into any courthouse or Federal building. You can carry into a law enforcement office if you are so inclined.
You need to be fully legally informed, wherever you go. It'll take some extra time out of your day. Good luck and study hard.
