PONTIAC, Mich.- Trainer Jerry Craddock holds up a chemical hot-pack that can be placed on the skin of hypothermia victims during Cold Water Boot Camp, a class updating Auxiliarists on the latest techniques for dealing with people who have been immersed in cold water April 1, 2011. Coast Guard Auxiliarists, who volunteer their time and vessels to help the active duty Coast Guard keep the boating public safe, came from all over the Ninth District and as far away as Alaska and Hawaii for the training opportunities available at the symposium.
