That's my daughter Julia's Specialized Hot Rock - her Xmas present from me and my girlfriend. We were at Park School in Mill Valley - I was taking turns stealing her xmas present and my son's (a skateboard.) Julia learned how to ride with no hands that day, too.
Words and Photo from Peter Nicholson (Side note: Peter used to look like Robert Smith in high school. His current look is a little tamer, but I really like his sneakers. Next time, we'd like a pic of the whole family on bikes - no hands!)
