The Coast Guard maintains more than 50,000 federal aids to navigation--the traffic signals and signposts of the nation's waterways. The primary components of today's aids to navigation are beacons--navigation aids that are permanently fixed to land--and their waterborne cousins, buoys. Their maintenance requires carefully coordinated teamwork. US Coast Guard Art Program 2000 Collection, Object Id # 200011, "Teamwork," Richard Ochs, watercolor, 15 x 22 inches
