EVO607797 sent me an E-mail, which, to my great shame, has only now been found by me. He would like to add:

We have a community in Northern VA called "Dale City" that was built in the Southern suburbs of Washington, DC in the 1960's. Super cheapo construction and standards; all-gas (even yard lights), all-aluminum wiring, FPE split-bus panels, no central air, (baseboard HW heat), you name it. Yes, there was (and still are) plenty of solid aluminum GEC's.

This community was built to provide "affordable" housing choices in what was then uncharted territory. They cut corners everywhere they could. Nowadays, these home owners are paying the price, big time. The houses may be still be affordable, but the maintenance costs are astronomical. Most of them are now cheap rental properties and have pretty much become ghetto areas.
