Automobiles offer excellent lightning protection. When no shelter is available, avoid the highest object in the area. If only isolated trees are nearby, the best protection is to crouch in the open, keeping twice as far away from isolated trees as the trees are high. Avoid hilltops, open spaces, wire fences, metal clotheslines, exposed sheds, and any electrically conducted elevated objects. A constant supply of pure drinking water is essential.
Serious illness can result from drinking unpuriifed water.
Protect your health. Don't take a chance on using water that you are not sure of. Thermos jugs, plastic water containers, and canteens are all satisfactory for carrying water. Be sure water is dispensed into each person's own drinking cup. In addition to having a bad odor or taste, water from questionable sources may be contaminated by microorganisms, such as Giardia , that can cause a variety of diseases.
