I took a photo of the direction signs for bicyclists to illustrate how bicycle friendly a city can be. There are several reasons I didn't ride while I've been here, but if I had chosen to ride, it would have been easy to rent one of the public-use bikes available in every neighborhood. Many streets have bike lanes, and the drivers seem to be accustomed to sharing the road. In fact, I think there may be a bike lane in this photo.
In addition, there are charging stations for electric cars readily available.
