I enjoyed playing there also, althought it's private they allowed some afternoon public play. Eucalyptus trees, ponds and some natural changes in elevation made it interesting although not very difficult.
Ignore the above I confused it with Lake San Marcos in San Diego area.
I have played Rancho San Marcos in Santa Barbara area also and enjoyed it very much, very natural setting many old oaks, great par threes and a couple of real tight par fives.
