Holding American citizens prisoner on our highways for hours and days always makes them sympathetic to your cause...
I know this is NO time to think of laws or rule of law BUT isn’t there some kind of statute against the banning of Interstate Transit?
Think it goes back to RR strikes and it became a Felony to block traffic.
People forget, the idea of Interstates is NOT so one has a quick ride to Grandmas house, it was basically designed and built for Military then Truck traffic being used for Interstate Commerce.
Ike’s ‘dream’ came about after he had a hell of a time taking a convoy across country and what should have taken days took weeks due to poor highway design, unpaved roads etc. The feeling it would work came from how he saw the ‘Autobon’ working.
