On our walk back to H's apartment after the de Young museum, we passed a group of people rollerskating. Actually, some were roller dancing. They were playing music that sounded like the Sugar Hill Gang, and some were pretty talented. I liked this lady's shirt. In case you can't read it, it says "Wake. Eat. Skate. Sleep."
I'm pretty sure Heather will post a video of the skaters on her blog, so check it out. (http://pinkpolkadotdiary.blogspot.com/2008/07/roller-skating-in-ggp.html)
