A thousand semis with trailers could easily shut down access to and from any city pretty easily. We could watch all the feds run out of gas and be stranded in the desert.
I watched the Taxis in Downtown LA do this many years ago, they literally CLOSED THE CITY, you could not drive anywhere.
Concern is the feds will treat this like Jan 6 folks. They will round up the organizers and anyone participating. Gonna get interesting.
