Lately, more and more Spanish cities are promoting cycling with bike-sharing initiatives or by building cycling lanes.
Not far away from my hometown, there is a lovely city, Girona, which has also taken up to promote cycling as a fast (and healthy) way of moving around. Last Sunday I went for a stroll with my family there and I saw what is for me a pretty good ad to promote cycling. The ad is created by "Mou-te en bici" ("Move around on a bike"), an organization which advocates sustainable mobility.
The translation from Catalan into English would be: Do you still drive a car? If you rode a bike you would already be there!
...this is where the ad was placed: in a place where all car drivers can see it!
