I would suggest the coast for a number of reasons. 101 has wide shoulders and most autos seem to be aware of and somewhat cautious around bikes. Food and lodging are plentiful. A number of state parks have bike-and-hike facilities that don't ever seem to be full. Plenty of hotels if you're not camping, but the camping is great. It isn't too difficult to get a ride or a bus out the coast if you don't want to ride there. Oh, and you can get bike specific maps that show elevation, camping, bike repair, mileage. It's all set up for you. That reminds me, I haven't done it for a while.......hmmmmmm......
