With help from Transportation Alternatives, a group of mothers and families known as Mobilized Moms led a car-free Central Park rally on Tuesday. Streetfilms' Robin Urban Smith says about 50 supporters, including Manhattan Borough President Scott Stringer and City Council Member Gale Brewer, came out in support of the Moms, who marched from Central Park West and 72nd Street to the Naumburg Bandshell.

The group plans to collect kids' artwork from the event, along with written correspondence, for a book to send to Mayor Bloomberg in hopes that a car-free trial period might finally be instituted.
