A 5-year-old girl saw the dust trail of the bus and pedaled toward it on a red tricycle. Three teenage boys came barefoot in swimsuits. A young mother walked over from her trailer with an infant daughter in one arm and a lit cigarette in the other. “Any chance there will be leftover food for adults?” she asked. It was almost 1 p.m. For some, this would be the first meal of the day. For others, the last.
