I didn't read the included-link's story, but last night some additional information was offered about these people. Good, bad? Probably gooder than badder -- but definitely using some poor judgment. The weed probably adds to the question of how bright they are, though. The basis for their "mission" appears to be true, but whether or not just -- that may be less clear. The main dude appears to be going through some stuff after the loss of his daughter, so...
But, man, they should have rented a car. Or took the wife's car. Supposedly, the reason for the stop was a broken windshield. In the two photos that I saw of the windshield area of the truck, I didn't see any damage. I'm not saying that it wasn't there, I'm just saying that I can see any. What I can see is a paint scheme that screams out "flaming lunatic gun nut on board" -- so, trying to drive that through the NJ/NY area was just simply insane.
