On the third day of our "totally not a beer trip" trip we went to our third brew pub, Lagunitas. This one is in Petaluma, CA halfway between Moylan's and Russian River and also right off 101. Very convenient place although it's located in what seemed to be an office park. Lucky offices. The sign is easy to miss as it's small, but we managed to find it. As you walk in there are tables outside and then a tented area in front of you.
