Route from Mammoth mountain, CA to Boulder, CO
Driving a 39' DP with toad from Mammoth to Boulderin Sept. My first concerns are the roads thru Nevada. The roads seem to be 2-lane hwy's. Route 6 is the most direct route. There is an option of hwy 93 for the last part into Utah. I70 over to Denver. That is another concern.
Are my concerns warranted? How are the hwys across Nevada? Vail pass? Other suggestions.
