Mexico City pushes for order with parking meters - Article Photos 4/6

CORRECTS DAY OF THE WEEK - Protesters hold signs supporting a "no" vote in an upcoming referendum about the installation of parking meters in the Condesa and Roma neighborhoods, as they block the road entrance to those neighborhoods in Mexico City, Saturday, Jan. 19, 2013. Here and in other well-to-do areas of traffic-choked Mexico City, authorities are trying to take back the streets by installing parking meters. Many are vehemently opposed, saying the streets are public and no one should profit from them. (AP Photo/Marco Ugarte)
