Do any cities in California have any large exclaves?

I have noticed that a few cities in California appear, on maps, to have exclaves (incorporated city in unincorporated county areas), but these seem to be only water treatment plants and wells. Are there any cities in California where incorporated land is unconnected to the city it is a part of? If so where, and what is the property?

1. Check out airports. Those are good candidates for exclaves.
