I joined 800 of my agency colleagues for an urban scavenger hunt/creative challenge made possible by the folks from
The Go Game. It was really fun--for the first two hours, anyway. Then the hot, humid temperatures made the constant running up and down Michigan Avenue in a black tee shirt and jeans really uncomfortable. I don't know if it was the sun exposure, a touch of dehydration or the spinning challenge that did me in, but I've had a headache since 2pm. And I don't typically get headaches.
