Every January, Geoff Parker hands his wife the training schedule for his mine rescue team. The training sessions get penciled into the family calendar, taking precedence over everything else. Parker's proficiency with a 28-pound breathing apparatus, designed to keep him alive for four hours in a bad air situation, could someday save his life, or the lives of co-workers at the Lucky Friday Mine in Mullan, Idaho. "He's doing a great service for the community," says Parker's wife, Kristin. "I never begrudge Geoff spending his Sundays doing mine rescue."
