For the past three years there's been a tribute to American Graffiti in Petaluma, California. This year marks the 35th anniversary and they are planning to recreate the famous "pulling-off-the-axle-on-the-cop-car" stunt at 4:30am on May 15. Here's a quick bllurb about the event from the website.
"Although portions of American Graffiti were produced in other Northern California locations, most of the memorable scenes in George Lucas’ timeless, coming-of-age movie were filmed right here in Petaluma in June and July, 1972.
Petaluma’s Salute to American Graffiti is an annual celebration of American Graffiti, classic American cars, cruising the “main drag”, rock ‘n roll music and the “happy days” of the ‘50s and early ‘60s. Produced by Cruisin’ The Boulevard, Inc., an all-volunteer, tax-exempt 501(c)(3) nonprofit California Public Benefit Corporation, Salute proceeds benefit our own community projects; schools; and other community programs that focus on the arts, history, safety and welfare of Petaluma."
