I worked many years for (the old) General Motors at the corner of Ellsworth and Elliot roads. Not for a GM dealership or some other auto-related enterprise, but at the GM Desert Proving Ground — “The DPG” as it was termed.
No, it’s not “the GM Proving Grounds” or something else, as is most often cited. You people and others in the media need to do your research. GM had many proving ground operations: one for cold-weather testing up in Canada; one for altitude testing near Pikes Peak, Colo.; the largest operation in Milford, Mich. — the “Milford Proving Grounds” (the S is very important, apparently); and the former Desert Proving Ground in Mesa, whose operations are now limping along out in Yuma.
The DPG began operations in 1953, and when I was transferred out to Mesa from Michigan in 1987, it was drilled into me: you work at, you work for, THE DPG, the Desert Proving Ground — even to the exclusion of General Motors Corporation. It was nearly a daily mantra, and you never mixed up The Milford Proving Grounds and The DPG. So you need to get it correct as you continue writing about new developments, and respecting old entities, out in the East Valley.
