Today's face-off pits two bus stops in southern California against each other.

We need your help to fill out the field of bus stops that will compete for nationwide ridicule (and with it, a kick in the pants for local streets and transit agencies who are responsible).

Will the companies be able to maintain safe bikes, provide good service, and stay financially viable in the long run? It's too soon to say. But in the early going, they are proving that plenty of people will use bike-share in a city where it previously flopped.

America is aging — by 2030, 20 percent of the population will be 65 or older, up from 14 percent today. It's a demographic shift with big implications for urban transportation. Older Americans drive less but still want to get out and experience their cities.
