Actually, as truck driver, I'm obligated to "produce my papers".
However, in a private vehicle, I'm not (see the 4th amendment).
As for the road, no sir, it belongs to me, and all other fuel tax paying
citizens.
All I know is, if you put anything inside 50 feet from the centerline, the state will take it, of whatever
they want to do, and you won't win ANY court case, if one is filed.
Maybe that's a state law, and I'm not sure exactly how it work on interstates...
I believe in individual liberty, and freedom, but with that has to come individual responsibility,
which, unfortunately is lacking badly in the percentage, so we all now have to pay the price.
I don't know if you saw the Stossel special the other day where he was comparing the US to the old Rome,
but the similarities were striking, of how Rome was right before the main downfall.
