It is common sense that your woodpile should be within a short distance of your campfire. The wood should be graded and arranged into different sections. Woodpiles may differ in appearance, from the simple 'stack-it-on-the-floor' to the more complex wood shed. Even a simple stack should be provided cover against the elements, even if it is only a bin liner pegged over the top of the pile.
Ideally you should have a store of kindling as well, this most certainly should be kept dry.
