From a centre outside of school. My parents aren't worried about the area we're going to, but the area the boys come from, and I do understand what they mean- on a previous expedition some guys managed to sneak on hand-rolled cigarettes. And it wouldn't be so much of an issue if there were girls in other groups, but out of ALL of us going, I'm the only girl. And on my Silver Assessment, I was in a group with two guys and one other girl, and my parents were fine with it, but they're not really OK with all of them being guys. My parents aren't overprotective at all, so when they do show concern about something, I do try to understand.
