L.A.'s roads have long been devoted to all types of honking, fume-spewing vehicles, but for one day this weekend, automobiles will be cleared from one route, leaving room for bicyclists, walkers, runners and other wanderers for the second CicLAvia. Along the 71/2 –mile route, there will be activities, including performance from the Invertigo Dance Theatre, organized bike rides, pop-up dodgeball and a happy hour hawking craft beer. If you miss this one, don't feel too bad: They're planning at least three more for this year. CicLAvia; route extends from Hollenbeck Park to Heliotrope Drive and Melrose Avenue. 10 a.m.-3 p.m. Sun.
