From the screen, it looks like the official title should be "Thousand Oaks, East" (I am intentionally omitting the "CA" as this is a CA forum). The other site is likely "Thousand Oaks, West". This makes much more sense for us non-locals who cannot tell the difference between Thousand Oaks and Westlake Village. Actually, it seems from discussions in these two threads that sometimes locals can't either!
Come to think about it, Carlsbad should be relabeled "North" and "South", though there has been no activity there at all.
