Castle Rock, home to about 85,000 people, is the seat of Douglas County and one of the fastest-growing towns in Colorado, about halfway between Denver and Colorado Springs. It is named for the butte that overlooks downtown, and Philip S. Miller Park, Festival Park and the Starlighting celebration on the Rock draw families from across the region.
The Outlets at Castle Rock and the Promenade shopping center pull in shoppers from up and down the Front Range. I-25 runs straight through town and US-85 heads north toward Littleton, so billboards here reach daily commuters to Denver, travelers between Denver and Colorado Springs and a fast-growing base of young families.
