First Time, Western USA

[Estelle641]

Hi all,
We're planning a 2 week trip from San Francisco to explore what the USA has on offer outside the main cities. We've been to a few main cities before, so we'd like to focus more on beautiful scenery, interesting places, easy drives. We're from South Africa, so this won't be repeated anytime soon. We have no idea which direction to head into, but would like to drive along the coast somewhere, visit those beautiful sandstone formations in Utah, Yosemite if possible, whatever you suggest ;)
Thanks !
