Wildfire Orphans

By Michelle Werts During wildfire season, oftentimes, our attention is drawn to the big stories: The evacuation of up to 12,000 campers and hikers in Angeles National Forest over Labor Day Weekend due to the 4,000-plus-acre Williams Fire. More than 7.6 million acres burned across the country as of August 31, 2012 — on pace […]
