Things I Didn't Know
There actually was a US Route 666, in the four corners area. It was renumbered under pressure from Christian groups, and for the pragmatic reason that people kept stealing the signs (I would love to have one). Apparently there was a horror film by that name, but it couldn't be as good as the classic Interstate-60, an exploration of freedom and slavery that is one of my favorites and should be on the must-see list of every libertarian.
