Bicycling advocates in Washington, D.C., are planning a memorial to honor a University of Michigan graduate student and safety activist who died after he was struck while riding there last week. "Please join us to remember Jim Pagels, a passionate urbanist and safe streets advocate, [the latest] to become DC’s latest victim of traffic violence,” according to a Facebook post by Handlebars DC. Rachel Maisler, an activist and resident who chairs the DC Bicycle Advisory Council, helped to coordinate the event, which calls for installing a “ghost bike” — typically a bicycle painted white in memoriam — near the intersection where Pagels was struck Friday, followed by a tribute ride and moment of silence.
