The code of the campfire says tool up. The U.S. Forest Service campfire permit says that you "must have a shovel available at the campfire site for preparing and extinguishing campfires." In addition to a shovel, I find that a grill or campfire grate, 18-inch utility tongs and small leaf rake all contribute to successful campfire.
The grill holds pots and skillets over the fire, especially where the Forest Service doesn't provide one. (It seems when I leave the fire grate at home the campground doesn't supply one!) The tongs efficiently arrange burning coals around in the fire. And with the rake, you don't have to use your boot to clear a five-foot area around the campfire.
The second part of the code says leave the campfire site cleaner than you found it. Pick up trash, rake debris from around the fire pit and see that the fire is dead out.
