Anyone who's been camping knows how dark it gets out there at night; I have been to some campsites that I can hardly see my hand in front of my eyes. Lighting is an essential when out camping. I have been camping for over 26 years and have found that everyone should have their own flashlight and a lantern or two for the campsite itself. Nothing worse than tripping over a piece of wood for the fire and falling when you can't see a thing. I always have two or more flashlights over the recommended one flashlight per person. That way when and if your batteries run out you always have a spare.
