New York City’s streets are clogged with huge, rude trucks that park where they want, hold up traffic, and bulldoze into anything that is in their way, and the pushcart peddlers are determined to get rid of them.

The pushcarts have won one battle, but can they win the war against a corrupt mayor who taxes the pins and prohibits the sale of dried peas?
