I've always wondered if Albuquerque had some incredibly difficult, confusing roads due to geography or something that
make navigation mistakes likely.
I don't always geek about broadcasting, but when I do, I prefer to also geek about roads...
US Route 66 was specified along a daisy chain of roadways that led from, as the song goes, Chicago to L.A., and while having it specified was convenient, having it paved was even more so. Much of the highway was eight feet wide, enough for one car; when two met coming in opposite directions, they'd pass each other slowly, one side of each in their respective gutter.
So upgrades were fast in coming - sometimes just widening the existing road, and sometimes requiring an entirely new (and often safer) path for the highway. So fast, in fact, that the mere possession of last year's map did not guarantee that you were on the road that was marked "US 66" *this* year, and in the arid southwest, the no-longer-current alignment started looking abandoned quickly. This was particularly egregious at a particular intersection in Albequerque, where over the course of a few years, the marked route for Route 66 required you to either turn left, turn right, or go straight, depending on the whims of that year's alignment.
For cross-country travelers - many of who were doing so to relocate into L.A. - the "wrong turn at Albequerque" was a very real concern.
