Tens of thousands of Colorado Springs residents forced from their homes by a raging wildfire are taking refuge with friends or family and crammed into hotels and shelters.
Army troops are helping firefighters protect the U.S. Air Force Academy from encroaching flames.

Shifting winds Wednesday challenged firefighters trying to contain the 29-square-mile Waldo Canyon blaze and extinguish hot spots inside Colorado Spring's western suburbs.
