In an attempt to solve our global oil crisis and so as to breath cleaner air, once a month, in cities throughout the world folks get together for community bike rides. In Washington DC, beginning at around 5pm on the first Friday of each month, bicyclists congregate in Dupont Circle for a 6 pm step off and bike ride through the city. This photographer has captured the assemblance in Dupont Circle on more than one occasion since the summer of 2002. Particularly, in recent months on 7 April 2006 and 5 May 2006. Join other bicyclists later this afternoon on Friday, 7 July 2006, for a 6 PM step-off from Dupont Circle for a special critical mass in solidarity with G8 protests in St. Petersburg, a G8 meeting focusing on the issue of Climate Change.
