Shelter, fire and water are the three keys to survival and maintaining your "core temperature control" (CTC). Shelter will protect you from the elements, water will keep you living for several weeks and fire will allow you to purify water, control your core temperature, cook or preserve food, signal for rescue and harden tools. This indispensable waterproof guide offers a common sense approach to obtaining each of these elements effectively and economically. Co-authored by noted survival expert and master woodsman Dave Canterbury, this is one of a 10-part series on survival skills. Made in the USA.www.waterfordpress.com
