I think there's still some overlap in kit for almost all circumstances. Many things are useful while at the fair or in the woods: Sunglasses, gloves, a pocketknife, flashlight, a water bottle, trail mix or power bars, etc.

But then most folks don't really think of the fair as a place you need a 'survival kit'. Cash is what you normally need to buy the true necessities for the fair...namely cotton candy and corn dogs!
