"The Boulder area features no shortage of men and women who bike to work. Not as many of them are working while on two wheels. Those who regularly cycle or run across Boulder County's highly variable topography have likely noticed, at certain times of day, the sensation of hitting warmer or cooler air pockets as they go. John Cassano, on his regular bike commute from Louisville to the University of Colorado, has experienced them as well. But, as an associate professor in the University of Colorado's atmospheric and oceanic sciences department, feeling the changes was just a starting point for Cassano." --Daily Camera
