SAN FRANCISCO BAY - Coast Guard Fireman Kristin Carfi, stationed at Station Golden Gate, blinds her eyes from the sun as she reports the status of a mock fire in the engine room to the coxswain while underway on a 47-foot Motor Lifeboat to conduct emergency drills, Thursday, Feb. 10, 2011. Carfi recently completed the machinery technician strikers program and expects a promotion to petty officer this summer. Each year the station performs approximately 600 search and rescue cases and approximately 300 law enforcement boardings, making Station Golden Gate the busiest station on the West Coast.
