I took close to 2000 photographs during my five days in Barcelona - yes I know, EDIT EDIT EDIT so I'm hoping you'll forgive me a little indulgent blogging.
Here's some citizen cyclists just going about their daily business. The thing I noticed the most was the way bicycles moved about the streetscape - traversing between roads, footpaths and cycle ways easily and without fuss. Bicycles, pedestrians, cars and scooters slowly moving as one through their city.
Such lessons to be learnt here about sharing and manners and etiquette.... and the fine art of slowing things down.
