How's your planning for this coming along? I'm looking to do the same trip starting next week (with absolutely zero planning) over 8-10 weeks. Pretty excited/scared.
From the little research I’ve done, seems like you just hit the 101 and head south. Loads of campsites, other cyclotouristes and easy navigation. Enjoy!
Planning Vancouver to San Fran (via Portland/101) beginning of October, following/bumping the thread for any further chat.
