Manuel, I recently participated in the search for a 5 y/o girl who was abducted and murdered. The search was sad enough, but I had to bring a dehydrated searcher back on my horse. The utter lack of preparation among the volunteers was shocking. Many schools here have adopted zero tolerance policies towards knives. An honors student was suspended for bringing a butterknife to spread peanut butter. I don't think your daughter needs a knife on this campout. I would verify the adult staff's experience and preparations however. I know some people who worry more when the car leaves to get detailed than about their own children!
