Just stumbled upon this post. I'm brewing in San Clemente for about a year now and have been looking for a local club to join. Haven't found one, but would be interested in starting one here in town. I'll send you a PM too.
Hey, I'm up in Laguna Hills... I'm a member of brewcommune (http://www.brewcommune.com/) and definitely recommend it... Most of the meetings are farther north in OC, but I can say that the brewers in the club are generally some very accomplished folks, so it's worth it.
