One of these sought-after settings is Boulder, Colo., the city claiming the top spot in our rankings. Boulder is a draw for many reasons, but undeniably because so much of its population is a result of the University of Colorado. But Boulder also has a draw outside the university. As far as environmental awareness goes, Boulder is one of the greenest cities in the United States, and the residents take advantage of the many outdoor recreational activities available to the students, professors and overwhelmingly young adult population.
