In the last bit of sunlight on a late afternoon during a trip back from California in April of 2011 I caught sight of this bus as I turned onto State Hwy 160.
The fading light was incandescent on the worn skin of the old beast. I just had to get a couple of shots.
Well, that may be the motto according to Wikipedia, but I've also heard "Over the hump in Pahrump" which I believe is from a local radio station.
