Snow rests on the parade grounds March 25, 2011, at Offutt Air Force Base, Nebraska. Be prepared for extreme weather conditions with an emergency kit containing items including additional warm clothing, blankets, mittens and gloves, extra socks, a flashlight, a candle and matches, non-perishable food, water, a shovel, and salt, sand or cat litter which can help melt snow or add enough traction to get moving again when stuck in the snow.
