They’re not pretty, but boots such as these—which I made from the foam of a truck’s
seats and some seatbelt webbing—might just save your feet from frostbite.
Food, including MREs: MREs—or Meals Ready to Eat—are available at
most camping stores and Army & Navy supply shops. This stuff lasts for
ever and often comes with its own fuel source for heating. Energy bars are
also a good option; look for ones that pack the most calories. Many people
ignore the importance of salt in their diets. Carry some with your extra
food or take along powdered energy drinks high in sodium to replenish
electrolytes.
Road maps (local): Make sure you carry maps of regions in which you
travel frequently, and before traveling to a new area, add a map of the
region to your kit.
