im part of OCMC, but let me tell you, depending on your age, it might be boring for you, im 34 and 80% of the club is about 45 year old+. The only thing i get from it is info on upcomming shows. If you want a couple of forums to check out,socalhorsepower.com and lamustangclub.com. I post regulary on both and meet up with both everyonce in a while. A few people about 30-40 cars)started meeting up at Frisco's diner on Wednesdays in City of Industry.
That is surprising. I would have thought they would take anyone interested in Mustangs regardless of age. I know I joined my first Mustang club when I was 16. Must be some sort of legal thing...
