That was my original point. Only OC residents who have identity-complex issues care about this. To everyone else, OC is a suburb of LA.
I was born in Upland CA. when I was born, except for Foothill Blvd, there was nothing but orange groves and vineyards all around. Upland is in San Bernardino county. Has a completely different profile to LA in just about every way imaginable - including crime statistics. It is in what is now the 909 (the 714 when I was growing up).
Oh, and now, just as it was then, Upland is a suburb of LA. I don't have any identity-affliction problems over this like many OC residents seem to have.
