ASPEN-- This tony resort town, set high above the heavily plied natural-gas fields of the Colorado Front Range, was the unlikely scene on Saturday of the latest clash in the running battle in the state over the controversial natural-gas-extraction method known as fracking. More than 100 anti-fracking protesters gathered outside the Democratic Governors Association meeting held here, waving signs, shouting slogans and staging street-theater scenes in an attempt to draw the attention of Governor John Hickenlooper and the other "important state leaders and presidential hopefuls" in attendance.
