Make no mistake—a sneaker campout is just exactly that: Camping out. And that means you'll need the necessary supplies. First, there's food and water. Pack a few snacks, or just swing by a drive-thru on your way there. Next, you'll want to bring a lawn chair and a blanket, especially if you're doing an overnight campout. If you bring absolutely nothing, be prepared to sit on a cold, hard surface with no chair, blanket, or food. Look on the bright side: At least you got them Js, though.
