San Clemente is a very fun course with a few intact Bell Sr. holes and the rest by his son. Tends to get a lot of play, so it might affect your timing. Strawberry Farms might be far from great, but is definitely among the best Orange County publics; this pretty much puts the state of public golf in perspective. Depending upon your open time, Goose Creek might work, and that is a really well designed Schmidt/Curley. This is near the worst LA basin traffic, but at the right time you can get from Goose Creek to John Wayne Airport in 35 minutes, but at wrong time it can take up to an hour and half.
