On the trail today, I saw the first notices for a total fire ban in all National Forests in Arizona.
No campfires, no charcoal grilling, no smoking outside, no fireworks. Did not specifically mention alcohol or Esbit stoves, but the ban is quite broad, and would seem to include them in spirit, if not in words. Naturally, when the trail passed a campground, I could smell smoke, but that might have been covered in the Exceptions.
Exceptions for fires in established cement FS fire rings/grills in developed areas, or where you have cleared a 5-foot radius of burnable debris.
