I am totally new to this so please bear with me. I am traveling Seattle to El Paso TX in mid May, and saw the great route that was given and plan to take the same route through Moab. Are there plently of 'gas stations' on that route? How is the motel/food on that route? And cell phone availabilty, how's that? Also, I am a single female (mid 60's) I'll be traveling alone, any advice?
