LOS ANGELES, CA - APRIL 16, 2012 -- Riders make their way east down 7th Street near MacArthur Park during the 4th Annual CicLAvia on April 16, 2012. Inspired by Ciclovia, the original weekly street closure event in Bogata, Columbia, CicLAvia opens LA streets to bicyclists and pedestrians, creating a temporary web of public space.
