we are getting ready to do a road trip, leaving Denver at the end of August. We are trying to plan the best scenic trip but want to get San Francisco, the beaches, napa valley wine country and all the way up to the washington border in our route. We don't care if we leave denver and to to the upper part of oregon first and then drive south along the beach to san francisco first, or the opposite of leaving Denver and going to San Francisco first then up the coast to Washington and then back to denver. Does anyone have any suggestions as to how we should plan to do this? Any sites that are an absolute must see? We have never done this, and are taking about 10 days for the trip. Any suggestions would be so appreciated.
