Decatur, Georgia ("Atlanta"...boy, everything is "Atlanta" these days...) has started it's own "yellow bike" program. Actually, it was not started by the city of Decatur, but a private individual.
The "yellow bike" progam is not unique, but it is interesting, and in my view, helps the cause of biking by making it ever more socially acceptable as a means of personal transport. It works like this: walk up to a "yellow bike," and if the sign on the bike says, "available," get on and ride to wherever you want (how about, San Francisco? )
Anyway, I would try it sometime, except for one thing: although they are adding new bikes all the time, their availability is comparable to Decatur parking spaces. But according to volunteers who keep track of the bikes, none are being stolen.
The bad news: one of the news anchors that commented about the story said (not a direct quote, but the spirit is accurate),
"Just hop on a yellow bike and ride! Or a "Big Wheel," how about that? HAHAHAHAH!"
Have you ever lost your audience without even realizing it?
