Tours

Last spring, my son took a tour with his classmates to Washington D.C. and had what he called an 'Excellent' time. These educational student tours are a super way for high school students to explore the country and get to know the other students in their group.
My son was in a social studies group, but there are tours for theatre classes, musical groups, and even custom tours. If your troop is large enough, something like this might be a viable way to explore part of the country you normally would not visit, or a way to cut down on vehicles and adults required. If you're really ambitious, you might even go on a tour to another country - remember World Jamboree 2011 is in Sweden.
If your son asks about going on an educational tour, I'd recommend promoting that as much as possible. I was pessimistic and figured it would just be a waste of money, but my son had a great time and learned a lot about the government.
