My wife and I are planning a 10-day late summer (late july/early august) trip where we fly into Seattle, spend 2-3 nights there (with friends,) drive to Portland, spend 1 night there, and continue on down the trail, stopping wherever is recommended until we eventually reach San Fransisco where we would like 2 full days.
We are OK with driving up to 4 hours/day as long as we don't feel like we're driving all day. We are interested in the wine country of OR and CA, as well as boutique/small town shopping, sightseeing and history. We know we want a full day in Portland and 2 full days in San Fran, but don't really know what to do in between. (total time in between is going to be about 6 days.)
Any advice would be appreciated very much.
