If you have ever ridden or considering riding a bicycle in Amsterdam, you might want to read this story in this morning's web edition of the New York Times: The Dutch Prize Their Pedal Power, but a Sea of Bikes Swamps Their Capital. I believe the picture of a massive parking lot for bikes is at the city's Central Station.

One thing it doesn't touch on is the increasing popularity of motorized scooters in Amsterdam. It's only exacerbating the parking problem since they take up more space.
