Overview

Boulder comes with plenty of stereotypes. It's a hippie town. It's a yuppie town. It's pretentious. It's the most beautiful place on earth. Like many preconceived notions, many of these have at least a grain of truth. But the real Boulder, the one behind the layers of perception, is simply a wonderful place to be.
