The Maine Warden Service said it will not charge a 17-year-old skier who was missing for two nights near Sugarloaf Mountain for rescue operations, which could exceed $10,000. Spokesman Doug Rafferty said Nicholas Joy of Medford, Mass., was neither reckless nor negligent when he went off the ski trail and lost his way. A review also shows the teenager showed skill at survival techniques as he remained missing Sunday and Monday nights. He was rescued Tuesday morning by a snowmobiler who went out looking for him, and was released from the hospital in good shape the next day. The search involved 85 people from the Warden Service, military, and trained volunteer groups.
