I'm never on the 101 in rush hour so I wouldn't really know. Distance wise it's not that far though

We live in Petaluma and DH commutes to San Rafael and it takes him anywhere from 30 - 45 minutes. Commuting from here to SF takes easily and hour, and that's with really good traffic. If your DH doesn't mind the commute, it's a beautiful place to live. I'm not sure if anyone has mentioned it but if you have Fastrack the GGB toll is cheaper.
We love living in Petaluma! It is very family friendly (and dog friendly) There are a ton of parks, and places to hike. Last month we celebrated Butter and Eggs day and they had a huge parade. This weekend they are doing a salute to American Graffiti. It seems like every month there is something going on.
The kids and I love walking around downtown, watching the Petaluma River, going to the local bookstore, etc. We have only lived here a year so we are still discovering new things. This is very different from where we used to live, so I am still very excited about it all.
