Before Dark, Except

Tom and Kobae would like to be home before dark, except....
A. Kobae is still going the wrong way and Tom doesn't recognize any landmarks as to where they might be.
B. Tom is a moron for thinking he could get Kobae to turn around at all.
C. Somebody set off a nuclear warhead at the Saddle.
D. Based on what Tom sees at the Saddle, the wind is about to pick up, it's going to get considerably hotter, but on the upside it will probably stay light for a while longer than Tom had originally thought.
