A ghost bike is a bicycle painted white and set near the spot where a cyclist has been hurt or killed as a memorial, and to remind drivers to share the road. Sometimes the bike sits alone, sometimes memorials or flowers decorate the abandoned bike, a visible reminder that life is fragile. There are hundreds of such memorials chained to fences and posts around the country. Last summer Genea Barnes began a road trip to photograph and document ghost bikes. Each year, the US sees more than 600 bicyclist fatalities, and more than 50,000 bicyclists report injuries. Ghost Bikes symbolize this suffering and these lost lives and challenge us to be more aware of our surroundings. The tributes began in St. Louis in 2003 and have spread to cities around the world including Boston.View more photos and continue reading at the Genea Barnes’ Ghost Bike web page.
