There's lots of good places to visit enroute.
Scapoose has a nice little restaurant with good Japanese and Western food, easy fueling and some nice people.
Cottage Grove has a few classic aeroplanes and a convenient hotel.
Roseburg is alright, but Grants Pass is friendly with a good 'club house' and interesting people as well.
Medford has a couple of FBO's, I tried one and was treated to excellent service. After being there nearly three days they charged me $3 a night parking

I'd bought fuel at Grants Pass and didn't need any at Medford! They lent me the car one night and the second night drove me to the hotel. I ate a load of their doughnuts, drank their tea, ate their bananas, watched their television and used their internet. I was embarrassed
Entering North California, (the state of Jefferson I believe), David will give you personal service with a good sense of humour and wit. He is a retired school teacher and with his wife Christine runs the FBO at Montague-Yreka, the little field near to the huge Siskyou airport. There's a couple of cars to drive into town where you can eat at Grandmas Place, and it's safe from any wolves. There's a bunk room at the airport where you can sleep for about $15 a night.
Redding is fun, a big airport with jets you can hire.
At Red Bluff you might be lonely as you fuel the aeroplane yourself.
Fresno's smaller field (Mc Laughlan???) has ARCAL, the ATC controller at the big Fresno Airport was disappointed when I went to the little place rather than his big place... One day perhaps!
The small Fresno Airport was the original airport, it's terminal is similar to Shoreham's terminal in England: Art Deco, and you can imagine the days of the old mailplanes, DC2s, and Curtis Condors... Reasonable greasy spoon food there...
Just a few ideas.
Don't be afraid of the big fields, they have excellent FBOs who give you an embarrassing amount of service at times, "but I'm only flying a little aeroplane"
At some of the smaller fields you'll get personal service and meet some of the nicest people you can anywhere.
It's a great experience, so try to take your time doing it...
