I was in Amsterdam last year, and one of the things I was most impressed by was that all the streets had separate lanes for bicyclists!
The Dutch love bicycling, and the city shows it. All the roads not only have pedestrian paths on both sides, but also bicycle tracks. Not just that, the bicyclists have their own traffic lights too!
They look quite cute, don’t they? (See the Green version on my Flickr collection – at the right). And, though they may be Red at times, they’re always environmentally Green!
