If you're planning on exploring much or driving through Adobe Town you better plan out your gas situation before hand; stations are few and far between. (Also 4wd uses quite a bit more gas than 2wd). The nearest stations would be Wamsutter and Rock Springs, WY and Baggs or Maybel, CO as far as I know. There is no gas on I-80 between Wamsutter and Rock Springs.
Good point! I think I gassed up in Craig before, Wamsutter after. I'll take a look at the map in the next few days and add in some details about nearby gas.
