X2 on going the other way... Pick up I17 SOUTH and then take the 278 EXIT at 169 to Prescott...
No big hills or loop backs this way...
Be sure to watch for the 278 EXIT - Not a very large Interstate intersection with NO business buildings around it... Only see what looks like one farm/ranch house on google maps haha...
If you miss it the next turn around is 10 miles south at Exit 268. I don't think I would take this exit road to get back to 169... Looks more like a JEEP trail road from google maps - turn around and go back up to exit 278...
