On the off-chance that someone believes that there is border security between US states but that these states are an exception.
The US doesn't have border security between states.
The closest thing to an exception is the "don't bring agricultural products into California" stations. However, there's a bypass lane for folks who stayed within 10 miles of the border, and no one checks whether someone is using that lane inappropriately.
The distance between Providence & Brookline is only slightly further than the distance between Dallas & Fort Worth. New England states are tiny.
My understanding is that the border security between those states is rather lax.
