When I last came here, in the dark final days of George Dubya, the Rough Guide of the time advised that “given the traffic, few visitors will actually want to brave the DC streets on a bicycle.” Since then, like much of the partly-civilised world, the city has started to respond to the wishes of those who want to get around without spending half their days in metal boxes. In fact the Capital Bikeshare website proudly proclaims the city as one of the US’s most bike-friendly.
