The scene: I was leading a multi-day river rafting trip with 20 young offenders from a juvenile detention centre in Oregon along with seasoned river guides and four prison officers.
By about day eight of the trip, things had changed. It was subtle, not dramatic, but nobody had become a saint. Fred (the little toughie) was still capable of stirring up trouble if he got bored, and some of the boys could still produce a put-down faster than a paddle stroke. But the river had been working on them.
