Welcome to Busytown where everyone is on their way to work.

The Busytown grocers stock and sell fresh food; the bankers keep the money safe; the doctors and nurses make sure everyone is healthy; the postal workers collect and deliver letters; the sanitation workers collect trash and recyclables; the lumber workers chop trees to make furniture and houses; and the workers at the docks, railroads and airports help transport people and freight.

But it takes even more careers and professions than that to keep this busy town running.
