"Wyoming Plagued by Big-City Problem: Smog"
"CHEYENNE, Wyo. -- Wyoming, famous for its crisp mountain air and breathtaking, far-as-the-eye-can-see vistas, is looking a little bit like smoggy Los Angeles these days because of a boom in natural gas drilling.
Folks who live near the gas fields in the western part of this outdoorsy state are complaining of watery eyes, shortness of breath and bloody noses because of ozone levels that have exceeded what people in L.A. and other major cities wheeze through on their worst pollution days."Source: Wash Post, 03/09/2011
