There are 2 courses in Irvine, CA that is not listed in your directory. Here is a web link: http://www.cityofirvine.org/depts/cs/commparks/specialparks/disc_golf_course.asp

Also, I have played a round at Anderson Park in Carson California. The address is 19101 S. Wilmington Ave. Here is a link to a city of Carson web page that gives the names of a couple parks with frisbee golf courses. I have only played at Anderson myself.
