First off, I'm amazed at how much more cycling there is than there was even a decade ago. We saw cyclists every where. Perhaps the warm weather contributed, but cyclists were hard to miss. It was not that way not so long ago.
Second, I was somewhat amazed to see just how HORRIBLE some of the cycling facilities were. A two-foot wide door zone bike lane on a street with speeds of 40-50mph?
Third, while I have not observed a lot of safe and assertive cycling any place I have been, only in LA (actually Torrance) have I observed people riding on sidewalks, against traffic, with no hands, while lighting a cigarette. Yes, there were pedestrians about.
Finally, it is nice to see old neighborhoods and how things have changed - or remained constant.
