I had the book and the AC maps. I left the book home since I decided I like the AC maps better. I picked up a bike map of the Oregon coast distributed for free by the Oregon Department of Transportation and liked it the best of all for the state of Oregon. Look for it in local bike shops of find it on line ahead of time.
I will say that I didn't care for the route that Adventure Cycling used between the Seattle area and Astoria. If I were to do it again I'd probably either try a more coastal route there or just start in Astoria.
Most places where the raccoons were bad there were critter proof boxes provided. At least there were in the portion that I rode (Seattle to San Luis Obispo).
