I asked my daughter, she said that when they break up into small groups for games, discussion, and prayer groups, they count off by number. That tends to mix the kids up a bit.
She did say that most of the boys in the group are the outdoorsy, rugged, hunter type, and there was one that didn't seem to fit in with that too well. His family just changed churches though. Hopefully he'll fit in better where he's going now.
