Yep. There are a lot of these out here in the southwest. I've even
seen a
few that were designated as street patterns, then during one of the
inevitable housing booms, were resurrected into actual neighborhoods.

Do you have any lat/lon coordinates?

It sounds like it could be an interesting Google Earth trip.


There's one at N32.554, W111.717. I have heard that there is one of these in this area south of Phoenix
that is an old World War II Japanese interment camp. Not sure if this is it. It doesn't look like it on Google
Earth (named streets and some houses).
