Jon,
Well, we’re in San Diego and our Scout Troop only gets to the Sierras once, maybe twice a year, so it doesn’t make sense for us to have alcohol stoves just for the Sierras. Besides, those trips are usually at least a week and for 8-12 people in our crew we’d have to carry a significant amount of alcohol fuel, partially offsetting the weight savings of the stoves. On PCT between the Mexican border and the Mohave Desert, many parts of it have alcohol stove bans (and our Troop has hiked several sections of the PCT). I also doubt Philmont would allow the use of alcohol stoves but I could be wrong. Thanks, CV
