Urban Challenge Boston 2003: Checkpoints.
Seems like a cool race to run.
Try out the questions, after the fact, to see how you would have done.
You can also try the trivia questions that determine your starting point in the race.
Robin and Karin ran the race and share their pictures.
I heard about this from reading [ Dan Pink's story, and on Fast Company's new blogwhich Heath Row told me about ]
