It's every Sunday, but more cars tend to show on the 4th Sun like dion said...and no I don't have the motivation to get up that early on a Sunday, so I didn't get too many pics of the 100K+ cars.
All you So-cal guys, i know this thread is old as hell but we should have a meet (or another one, not sure if it ever happened lol). I live around disneyland or so, id be down to meet up with some people if anyones interested...
