Chino, CA : not in "The O.C." and apparently not where chinos come from. Mandy, George and I watched the premiere episode of what Fox is billing as the new "90210" the other night, "The O.C.," which turned out to be a mildly enjoyable teenage "Less than Zero" crossed with TRL, a dash of "The Outsiders," and lots of low-rise pants. I found it was not quite bad enough to be fun, at least, not yet. In any event, residents of the real life city of Chino are apparently very pissed that the fictional kids of Newport Beach continually malign their town on the show. Ouch.
