As the parents of active eight-year-old triplet boys, my wife and I tend to get a little nervous about school field trips. Case in point: Their elementary’s recent outing to Squire Boone Caverns near Corydon, Indiana. I have tremendous confidence in the teachers and staff at our school, and yet, it’s just so easy to imagine the phone call. The teacher’s anxious voice. The attempt at being honest, yet reassuring. The name of one of my children, followed by the phrases “separated from the group,” and “somewhere in the cave.”
