I have a lot of respect for BSA camp Rangers and look forward to learning new LNT techniques from them. Infact, we usually have two or three scouts who are Philmont Rangers each year. So I know what they go through. But sometime their maturity lets authority go to their head.
During one trek, the ranger decided to show off his fire skills at the evening fire before lights out. He poured some stove fuel on his hand and ignited it to show (show off) how the skin of his hand would not burn. Ironically this was after he led a Thorns and Roses discussion. The crew was careful to how they responded to his demonstration of physics because they knew the adult was going to have some words about fire safety. I don't like pulling authority on youth authority (he was 19) because it turns the relationship from the Crew Leader of a Crew to a Crew Leader of a Crew and adult. And that is what happened here. This Ranger was really very good and a good role model for living in the back woods, but after my very few words about safety, he treated me different the rest of the trek.
In a few words, scouting is about giving young people the confidence to behave adults. But sometimes the success of our confidence feeds over into our egos. Correction or our Egos hurts a lot worse than redirection of our confidence. I prefer a scout learn from his own mistakes without adult intervention because he learns the lesson faster if he doesn't have attend to wounded ego. But sometime humility needs to be fed as well to learn how to behave like and adult.
I only have a couple stories about loosing my cool because I am pretty tolerant and laid back with behavior. At most high adventure scout camps, the Rangers typically inspect each person in the crew gear to insure the crew is prepared for the trek. We are a backpacking troop and the Philmont Ranger was impressed with our preparedness. But he still felt the need to show his authority, so he picked on one scout who brought a personal backpacking stove and proceeded to chew him out for bringing more stoves than recommended for the crew. Our crew knew about it and welcomed the extra weight of the stove because the scout's mom and dad gave him the stove for his birthday just before we left for the trek. We would have brushed off the Rangers suggestion except he made such a big deal over it. It wasn't what he said because technically he was right. It was how he said it. You could see it in our scouts eyes, he felt bad for forcing the rest of the crew carry the extra weight. I took the Ranger for a walk.
Over the years of Scoutmastering, I developed the skill of not letting my emotions react before spending time to calm myself down. But that situation got to me and even the scouts said they had never seen my face so red.
Sometimes the rangers don't always get it right.
