Ok....I will wear clothes and no I'm not going anywhere near New York City.
Like said MD is touchy depending on local police. These days with computers I assume if a LEO wants to run your plates for whatever reason, the data bases may just come back with info that you are licensed to carry in whatever State.
Assuming you get through MD then PA with maybe trouble, maybe not...
Some states like said allow you to carry through if locked in a lock box in the trunk. Problem....my 2019 Ford Explorer has no trunk..it is a SUV with all areas accessible so I suppose it would be up to a local judge you are standing in front of to interpret whether you "had access" or not.
In any event, also as posted numerous times... New York is the problem. Which is actually funny for me at least because when the sitting Court Judge of Allegany County, New York issued my New York permit to carry a pistol in January 1971 I was told that it was a "lifetime" permit. No expiration, no renewal, and since I have never received any notice of revocation from New York State, I suppose one could assume that it is still good to go.
Nope...........I'm not in the mood to test it!
I do have (did have) a New Jersey permit also all signed and stamped by the officials of Camden County where I lived and worked for several years, but alas....that one was automatically revoked upon me surrendering my NJ auto plates and NJ Drivers License when permanently moving to Virginia in 1988. Those terms were in writing on the NJ permit if I recall. I'll have to dig it out of files and see if the photo is as scary as the NY one
Like said....it is now 8:07 am Monday morning and sounds like wife is ready to go (put my stuff in the car last night) so see all you fine folks later (travel with my old laptop so I don't miss any good Forum treasure pics).
Have a great Turkey Day!!!
