Survivalist Tip: Since power and utility infrastructures most likely will collapse on or immediately after December 21, it’s imperative to have some light source besides matches, sunlight and a full moon. Therefore, stock up on some battery-operated lanterns. And, I certainly don’t mean those decorative types you hang outside your patio during cozy outdoor dinner parties. They may look nice on cool summer nights, but they’re not practical. Sturdy lanterns can withstand heavy winds, rain and being used as a defense weapon. Have at least 3 available. Besides, there are few things more frustrating than trying to find chocolate in the darkness.
