Every Tuesday night, Joan Cheever hits the streets of San Antonio to feed the homeless. In a decade, she's rarely missed a night. But on a recent, windy Tuesday, something new happens.
The police show up.
"He says we have to have a permit," Cheever says. "We have a permit. We are a licensed nonprofit food truck."
Cheever runs a nonprofit called the Chow Train. Her food truck is licensed by the city. On this night, she has loaded the back of a pickup with catering equipment and hot meals and driven to San Antonio's Maverick Park, near a noisy downtown highway.
