We occasionally come across mysteries on Yahoo or Google maps showing vanished Inland Valley communities like Grapeland and Rochester and Narod. But here’s a new mystery: Google Maps is showing a second Pomona probably 20 miles west of the real thing, out in Rosemead near the San Gabriel border.

Life in this second, phantom Pomona, it must be admitted, would have its advantages. Our version doesn’t have a decent Chinese restaurant, and this new one has dozens.
