Coast Guard members aboard the Cutter Bristol Bay's small boat pull two struggling swimmers aboard the boat during the annual unsanctioned Jobbie Nooner boating party at Gull Island in Lake St. Clair, Mich., June 26, 2015. The Coast Guard is often on scene and prepared to respond during large unsanctioned marine events known for drawing crowds of swimmers and boaters in small areas.
