If you're going to venture into the Arizona backcountry snow this weekend be smart. Carry extra food, water and blankets. Carry extra fuel and travel with more than one vehicle. Bring a shovel, tow straps and a winch. Tell someone where you are going and when you'll be back. All of this and more applies to any off-road trip, but snow creates it's own unique challenges that many here in Arizona are not used to.
