Monique Williams McCoy greets everyone walking down Cleveland avenue like a neighbor.
"Hey y’all!" she calls out. "You coming over to check it out today, right? Over to the mobile market?"
Williams McCoy has lived in this part of Columbus, Ohio, for most of her life, and she’s familiar with how hard it can be to shop for groceries here. She works for Local Matters, an organization that tries to improve food education and access.
