From early spring to late autumn, dozens of cyclists meet for 'alleycats': unsanctioned scavenger hunts–turned–races sprung by daring local bike couriers onto D.C.'s unsuspecting streets. They make for exhilarating spectacles and welcoming, if temporary, multiracial, multigender, and cross-class communities. They have also persisted through, and grown alongside, shifting economic pressures on bike couriers, waves of gentrification that have made D.C. wealthier and whiter, the growth of the queer community, and a changed urban infrastructure that has witnessed both more bike lanes and more pedestrian deaths in recent years. Since their introduction to D.C. in the 1990s, how have these 'alleycats'—and the community that organizes and races them—adapted to these considerable social, economic, and geographic shifts? Do their multiracial, multigender, and cross-class participants reflect a truly open community? And at a time when the District is trying to reshape its urban infrastructure to better accommodate cyclists and pedestrians alongside cars, can advocates for safer and more orderly streets learn any lessons from daredevil racers who periodically reclaim them?
