I did not know that, thanks.
Should have added Maryland to my list, they have gotten just as bad as the others.
If you travel I-95 frequently from Whitopia (ME-NH-VT) to the Swamp, as I do, the Blue Wall of CT-NY-NJ-MD is a massive inconvenience (I have a VA permit).
Connecticut does, in theory, have a non-resident mechanism, but you have to get it from the police chief of a town, which, if you have no presence in the state is impossible. NJ has one but AFAIK has never issued one. MD and NY do not.
