In this activity, you and your team will have one hour to find control locations in Detroit using a map and (optionally) a compass. For the nerdly amongst you, this is the NP-complete Prize Collecting Traveling Salesman problem, which has a respectable and fascinating literature, as well as mostly untapped applications in bioinformatics. This is a fun activity for all, and you can approach it as a gentle walk in the park with your family, or a chance to compete against your colleagues. All ages welcome; under 18 must be accompanied by an adult.

Things to bring: a compass (optional), walking or hiking shoes, appropriate outdoor gear for the weather.
