52-years-ago an African American woman from Alabama did an extraordinary thing.

On december first, 1955 42-year-old rosa parks sat quietly on a bus in montgomery. She was sitting just behind ten seats reserved for whites.  When those seats were filled a bus driver told parks to give up her seat to a white man.

She refused. Parks was arrested.

But her actions spawned a national civil rights movement against segregation. Saturday LTD dedicated one seat on every bus, to commemorate the day and honor Rosa Parks.

Parks is often called "the mother of the civil rights movement." She died two years ago at her home in Detroit, Michigan. She was 92-years-old.
