Turn back the clock this Friday and Saturday when the glory days of tail fins, poodle skirts and Brylcream are resuscitated in Petaluma. “Cruisin’ the Boulevard” is the 12th annual salute to “American Graffiti”. If you’ve got a pre-1975 vehicle come and show it off. If not just join the music, food and festivities. Friday is a free kick-off. Saturday includes a Classic Car Show as well as a Cruise for $62.
