From the south: If you're on the 101, turn east on to the 37 towards Vallejo. Head about 4 miles and turn north onto Lakeville Road. Drive up another 2 miles and ignore the first "Old Lakeville #3" sign. Go up another mile and a half and turn east onto the second "Old Lakeville #3" to find us.
From the north: Head south until you get to the intersection of Highway 116 East and 101 South in Petaluma. Head east on 116 and keep on the same road after the fork, follow the route that sends you toward "Vallejo." Head south for about 2.5 miles and turn left onto Old Lakeville #3 Road.
There is no real parking but you can park on the dirt next to the row of eucalyptus, or wherever else you can find near the meetup point.
