That's kind of the point. The Blackhawk thread spun off the tracks (I think) when someone related the ban to the constitutional right to travel, I cited the ninth amendment basis for the right, and some took exception to the long-established practice of interpreting the Constitution in light of modern realities, rather than remaining mired in the 18th century, which is fashionable among some political types these days. It went downhill from there. An entertaining and informative twist, it was.
