In the olden days, 30 years ago, it was an all male outing but times, they change.
An adult leader in the council was killed sleeping in his tent when the wind came up and a tree blew over.
Stuff happens. What are the odds though?
When I had my own sons in scouting however, late 1990s to mid 2000s, there were far more moms involved than dads. I'm talking on the camping trips as well. I believe this was due to lack of volunteers (from the fathers).
As well, Boy Scout camping was much different for my sons, likely due to all the mothers involved. No pocket knives were allowed. Only adults could start or tend campfires. No archery. Definitely no target shooting. All mainstays of my camping experience.
