Bicycling 1:00:00 
To work and back, and to Fresh Pond and back. Really felt like a slog coming back, which is probably a good thing.
The score-O went really well. The students had been read the riot act by their teachers about their behavior, and were much better behaved. Also, the activity was simpler, and they had experienced this format before.
Katia, Ethan and Diego helped. Ethan hung the controls, made the courses, printed the maps, etc.
