As an Arizonan, it was only until 2 years ago in my Appraisal practice that I came across these crosses in Arizona City (south of Casa Grande). Really cool to see in person!

While the article does not really state anything, just positing more questions about its actual use, it seems like it is anyone’s guess due to the nature of the primary sources that knew the program being retirees or that the government gave this article writer all they felt comfortable with.

This makes me wonder: How many of these types of programs existed through the Cold War?
