Echoing the Situationist way of spreading a message with humor, the BBC Naked riders take to city street reports that
"about 500 cyclists stripped off, many adorned only with body paint slogans, for the third annual World Naked Bike Ride" in Brighton
where "the cyclists were campaigning against the use of vehicles and their damage to the environment" on June 7, 2008.
A number of other rides are still to take place in the UK (Sheffield on June 8, Manchester on June 13 and London plus Cardiff on June 14).
In the US, amongst the cities listed for 2008 are Asheville (North Carolina), Boulder (Colorado), Chicago (Illinois) and Portland (Oregon) all on June 14.
To spread the gospel on their environmental activities and share their calendar of events they even set up the Naked Bike Ride Wiki where I learned that most events in the Southern Hemisphere took place on March 8 and 9.
It also gave Belgian artists Léa & Titom a chance to display their talents with a series of Ciclonudista posters such as the one above.
