Routes from San Francisco to Petaluma
I'm planning on riding from San Francisco to Lagunitas Brewery (in Petaluma) in a few weeks. I'll be going up on a Saturday and returning on Sunday (likely taking the ferry from Larkspur on the return).
I'm trying to decide between two possible routes. Google Maps suggests a route through Fairfax and Nicasio, which sounds reasonable.
I also found a blog post with a different route that goes through San Rafael and along Novato Blvd (Google Maps link). The mileage is slightly longer, but I trust it a little better since it's a personal recommendation.
Anybody have any thoughts on the routes? Or a suggestions for a different route entirely?
Thanks in advance...
