TEXT: Cement blocks and buckets block off parking spaces along a street in the Condesa neighborhood of Mexico City, Friday, Jan. 18, 2013. Every day before dawn, dozens of men appear in the Mexican capital's hip Condesa neighborhood and block off parking spaces along entire streets using water jugs, cardboard boxes, buckets, crates and even blocks of cement. 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. On Sunday, Condesa's residents will decide in a referendum whether they want the meters on their streets. (AP Photo/Eduardo Verdugo)
