Vincent Vuong, a second-year biochemistry major, sits near a poster commemorating Rosa Parks' 50th Anniversary of her refusal to give up her seat, while riding the C line Unitrans bus to class. The front-row seats on all Unitrans buses were left empty Dec. 1 to honor Parks' groundbreaking act of civil disobedience in Montgomery, Ala. Each seat featured a picture of Parks, noting how she changed the course of history when she did not budge from her seat.
