Utah is amazing, in that they have a wonderful system of county roads that cross some of the most spectacular geography around. It is a big moneymaker for the economy. The markings are cryptic, a good map is recommended for this reason. “C392” doesn’t help much, but it might run 80 miles, there are thousands of miles of good graded dirt road, suitable for high clearance 2WD even. Bring plenty of water, camping supplies. Oh, if by chance one does need a tow, it starts around $500. Really only an issue once “off road”.
Tons of excellent exploring to do.
