Survival
Ya know...for being a field trip, and for the field trip to be for teenagers, Chicago went amazingly well. I am fortunate that these particular teenagers are more mature than the average kid that age, so after the "tour" of what they had to see, I was able to let them roam the museum on their own and have them meet us when we planned to leave. The great part is that it worked, thus being able to spend time in areas I wanted to see. I even got to sneak across the street for some shopping at the art gallery. I still wish I drove separately so I could have spent more time in Chicago though...
