Louisville is the "current" best model for what can be possible for urban cycling, and what made it possible was a bold vision by their mayor, Jerry Abramson.

The Louisville cycling community didn't happen by accident. It was made in large part from a conscious decision by a leader in government which influenced infrastructure, and then by the citizens buying in to that vision. This is just excellent and I'm surprised Louisville doesn't get more attention nationwide for the process in how it got there. Once it reaches the point where the citizens began to reap the benefits and proudly identify cycling as part of their city offerings, it takes on a life force of its own. This is the new Portland and it keeps getting better. Congrats.
