We are not familiar with the weather conditions in USA. We are Planing to go from Chicago to San Francsico via:
Yello Stone NP
Salt Lake City
My fear is a little bit the weather. I do not want to get stuck in the Rockies. Do you think this trip is possible whithout a 4x4 vehicle. We are planing to leave Chicago on the 7th of September and to be in SF on the 18th of September.
Any comments are welcome.
