Wearing 60-pound backpacks, a platoon of prisoners marched Wednesday, Oct. 11 along a narrow trail at Santiago Oaks Regional Park in Orange. Then the dozen or so inched their way up a steep hillside blackened by the devastating Canyon Fire 2. The mission for the minimum-security inmates from the Fenner Canyon Conservation Camp in Valyermo was unglamorous. But it’s essential: Extinguish hot spots and clear brush so the blaze won’t kick up again. And though their freedom was fleeting, they relished the tedious work and the chance to be outdoors.
