Cycling advocates in Guadalajara, Mexico were fed up with the local authorities inaction on creating a safe biking environment so they took the law into their own hands. Their efforts to create a bike lane system in the city are captured in this video.  Treehugger has all the details on the guerrilla cycling scheme.

It’s not the first time concerned citizens have protested in this way but you do have to wonder whether bike advocates in, say, a major US or European city, would be able to pull of such a stunt without attracting the attention of the authorities?
