This Sunday will kick off six Sundays of car-free Sunday Streets, which will take place in various parts of the city. This Sunday's route will extend along the waterfront from South Beach Park to Aquatic Park, and the event goes from 9 a.m to 1 p.m. There were two successful Sunday Streets last year, which drew over 15,000 people each weekend.

Participants will engage in activities such as dancing, yoga, skating, biking, walking, hula hooping, recreational sports, piano-playing on a trike, and people watching.

Sunday Streets is also looking for volunteers.
