We have a club, "Learning to Fly" in Mission Viejo, SOUTH Orange County. I know it's a "schlep" for you guys, but I live in NORTH Orange County and it's a bit of a schlep for me too. HOWEVER, it's WELL worth it! We meet twice a month. I think it would only take about an hour or so for you to get to us.
