CORVALLIS, OR
Beautiful, earnest, and very, very green
Population: 51,388 
The vibe: As small towns go, you don’t get much greener than Corvallis. This Willamette Valley town happily took up the Corvallis Energy Challenge, where residents strive to use the lowest amount of energy in their homes. With two LEED-certified buildings and more on the way, OSU is listed by the Kaplan College Guide as one of the nation’s top green universities. Every downtown block seems to have at least one eco-friendly business. According to resident Collin Dunn, blogger for pioneering green website treehugger.com, Corvallis is the perfect place for those “who want to live in tune with the seasons and natural rhythms of the planet.” –Allison Arieff

I don’t know if this is true, but I have an impression in my mind of Oregon and Washington in general as being very eco-friendly areas. Having grown up and lived on the east coast my entire life I’d love to visit and find out!
Realy I hope that this be true, but we need to expand this class of towns around of country.
It is a great town if not for the mortgage crisis.
