I can still remember the day I told you about Velib, this bike sharing system that the Paris town hall implemented throughout the city to stimulate the use of non polluting vehicles (instead of cars and motorbikes). Well, it's been exactly 6 years, as Velib celebrated its 6th anniversary last Monday... One thing is sure; it's a success! More than 250 000 Parisians subscribe to the service on a yearly basis, one Velib is rented every second within greater Paris and the oldest user is... 88 years old! Tourists also use it, of course! Look at the chart they have here if you can read French. As for me, well I tried it once, about 5 years ago, but never since the!
