Hi John and Welcome,
I've been toying with the idea of organizing a Southern California audio club. It would be different from the existing Los Angeles and Orange County Audio Society in that you would not have to be wealthy, brag about your $30,000 speakers, or $10,000 cables, or in any other ways be a snob. We would also welcome DIYers as an important part of the group, which they do not.
Let me know if you might be interested. I'm trying to decide if it's worth the time required to get it organized.
