R.G. Williams steers a city bus through Louisville's streets with ease.
His confidence behind the wheel comes from more than 15 years of experience working with the city's transit authority.
Williams started working as a driver and is now a supervisor.
But his history with TARC stretches back to his youth, when he was a regular passenger. From his home in West Louisville, Williams would take the bus to school, to the mall and to visit friends.
But a trip he took one fall day in 1990 was anything but usual. And it served to frame the rest of his life.
