According to a Gallup poll, the city with the best well-being in all of America is Lincoln, Nebraska. With a proud composite score of 72.8 on Gallup's well-being index, Lincoln beat out the perhaps more natural choice of sunny destination city Boulder, Colorado by one-tenth of a point. Another mountain gem Burlington, Vermont followed close behind. Lincoln, on the other hand, was originally settled because of proximate salt flats and marshes.
