COLORADO SPRINGS, Colo. (AP) — With evacuees anxious to return, firefighters worked Sunday to dig up and extinguish hot spots to protect homes spared by the most destructive wildfire in Colorado’s history.The labor-intensive work is necessary because extremely dry grass and trees could quickly ignite if wind stirs up hot spots in the densely wooded Black Forest near Colorado Springs.Firefighters did get some help from the weather as steady rain moved through the area Sunday afternoon. But that weather came with some lightning, which sparked a small grass fire near one home.“Every bit of rain helps the crews mop up. It’s just adding another nail in the coffin,” fire spokesman Brandon Hampton said.Nearly 500 homes have been burned by the 22-square-mile fire, which is 65 percent contained.
