Choose the right center
The map starts at the Colorado State Capitol (39.7393, -104.9848). A step on the west side of the Colorado State Capitol is marked as being one mile above sea level. Distances west into the mountains are slower by road because routes follow canyons, so plan mountain trips with a routing tool.
The place shortcuts run a search; they are not neighborhood outlines or claims that a whole neighborhood is inside your circle.
