Father Mike Lopez’s voice is effusive and booms for all to hear. On a Saturday afternoon, after a shock of sub-zero cold, he can be seen exiting an emergency-red colored van with the words “Community Response Vehicle” written across in yellow. A small group of volunteers follows him, pulls out plastic tables, a plastic bag filled with coats and a large thermos filled with hot noodle soup. A small line develops, here along Knickerbocker Avenue and Starr Street, in front of an entrance to Maria Hernandez Park.
