We have a drop or two Q4413 indicating high threat level and Cheyenne Mountain, CO. I understand these poorly.
Is the CO bunker referred to as castle_rock?
___________
I lived in Denver for 30 years. My memory is “Cheyenne Mountain” what the bunker has always been called. Commenter Mile-Hi can confirm or correct. Castle Rock is a stunning flat-topped rock mountain with a small town at its foot. It is located 40ish miles north of Cheyenne Mountain just east of Highway I25. It has no military purpose that I have ever heard about.
Spot on, SW. And I’m glad you made the point. I thought of Castle Rock, CO but it doesn’t fit the Q post. No tangible relation to Cheyenne Mountain.
65k in restricted terrain. Way overcrowded. Had 15k when I moved there, 50+k when I left.
