One of the reasons we went to San Francisco, and what really started our trip planning process in the first place, was that one of our friends had been picked, by lottery, to walk in the Nike Women’s Marathon. 13 miles… impressive. We went to Union Square with her so she could pick up her race stuff. What a crazy scene that was. Tons of people wandering around, in lines, getting free samples of chocolate and some strangely cardboard like cereal. Quite the zoo-ish atmosphere.
