B - Wonders whether she should consider a tour?
Of course. Oh, while you are in Portland, drive a few miles east to Hood River, and along the way, stop at bridal veil falls and hike up it. spectacular views. go to hood river. watch the windsurfers and kite surfers a while. eat more good food. cross over to the Washington side, and start back. keep your eyes peeled on the left for a tall natural spire. don't remember the name. But it is a rock tower that you can park and climb. Views from the top are worth the trip all in themselves! Great day trip.
If you wanna make a grand tour of the west coast, plan to drive from Portland all the way down to LA along Highway 101. Detour slightly through the Napa valley for wineries and wine tasting. San Francisco. Monterey Bay. Beautiful scenery the whole way, and several BF friends when you get there!
While in SoCal, might as well swing over to Arizona and look at the Grand Canyon. And JohnW and friends. Will take you through some desert and windmill farms (they plant them from seed!)
If you've got the time, potz around downtown Portland a couple of days. Drive a few miles north and take in Seattle, doing the same. Both interesting but very different cities.
Plan to bring plenty of TIME! Woman Seeking God's point is a strong one. All these routes mentioned, especially 101 all the way down, and all over Oregon, are just full of these small towns, MANY of which are just chock FULL of fun things to do, see, eat, and experience, as well as fun, interesting, and off-beat characters to meet.
Don't forget the natural hot springs in the woods...
