My son, daughter in law and grandson live in Castle Rock. The only negative is that housing is very expensive there. It’s a boom town. I lived in Colorado from 1980-83 and met and married my wife there (we met working at St Joseph Hospital). When we were there, Castle Rock only had a population of 4,000. Now it’s 55,000 and growing, construction of new homes all over the place.
C. Rock is just far enough away. At least for now. And you’re right, that area is pop’n. Get away from I-25 and that is a pretty part of the world.
