Sorry if this has been asked and answered before, but I couldn’t find it on the forum. I’m a leader with a pack that recently attended an overnight council event. Our committee chair notified us at the last minute that she would be camping with another pack that she has friends in, rather than our own. She does not have a child in scouting this year, and camped with them on her own. The rest of our pack is a bit confused. Is this normally allowed?
