I appreciate everyone's feedback; for the theory provided by T2Eagle, as it specifically addressed my question, for the detail laid out by Fred, for Pacan's reminder that scout safety is priority, and for DuctTape's welcome into the community. Others may have missed the mark on my post but that's ok, your input and suggestions are valued too!
To be clear, I have no concern that the troop is not going to organize an event that meets this requirement, and I did not intend to imply as such. Just stating that it hasn't happened yet but also, since my scout is eager to pursue his hiking and backpacking merit badges and this requirement (9b) coupled with the example in my original post could be a great opportunity for him to get his feet wet in preparation for both of those merit badges, it is unfortunate that it would not/could not/may not count towards Camping 9b if not done as part of a troop/patrol activity, which is why my question was phrased as such.
To address the importance of having the scouts lead the planning, no disagreement there. We sometimes find they need some gentle guidance to let them realize the same outcome that you "expected" all along, and there is nothing wrong with that. For example, if a troop or patrol needs to plan a hike to meet a requirement, that can be done literally anywhere. If you give them three options for where they can plan it and suggestions of how they can plan it, then they can decide which one they will plan, and then they will have met both the requirement and the spirit of the intent, all while staying well within the limitations of the SM/ASM. Long run-on sentences but I think we are all in alignment on letting the boys do their work.
More simply put, I am registered with both my younger son's pack as a DL and with my older son's troop as a MBC. Any independent activities that my son does, get prior approval for and signed for by other leaders, be it SM/ASM/or another MBC. However, as a MBC myself, I may one day be challenged with the same question I posed above, and I want to be prepared to defend the requirement's intent as written, which I why I ultimately joined the forum and asked for a discussion on the matter.
Thank you to all who responded, and again, looking forward to many more conversations with you fine people.
Sincerely,
🔥🔥🔥🦅
