If you want tales of debauchery, I could tell you about the time my troop was rafting and we saw about 5 rafts full of topless collage girls pass us.
We never had any luck with debauchery, though lots of fun times.
When I was in Rangers though, we did try to convince our leader to let us advance an invite to go camping to the Venturers…
Its more being silly rather than anything else! My local Brownie Pack/Guide Group, with which I’ve been involved was celebrating their 25th anniversary, and were having a party. Said party involved a massive game of pass the parcel. Anyway, it stopped on me (deliberately I think!), and I had to do the forfeit, which was to dance the Macarena with the Girl Guides. So, there I am, dressed in salwar kameez, dancing the Macarena with a bunch of 14/15 year olds. Scariest thing was, I knew how to do the dance better than they did.
