Waaay off in the distance, beyond the un-grid of this subdivision, is downtown Denver. Beyond that are the Rocky Mountains. That sense of being sort-of-near spectacular sights while still being trapped within cul-de-sacs is one that I expect is pretty common to people who spent some amount of their childhood living within such developments.
Dune’s naturally occurring “Shield Wall” always seemed a bit fictional to me—until I saw Denver’s metropolitan area from above. Look at that sharp divide between mountains and the valley floor!
