The Blue Line is a light rail line running north-south route between Long Beach and downtown Los Angeles passing through Downtown LA, including South Los Angeles, Watts, Willowbrook, Compton, and Long Beach in the Los Angeles County; it is one of five lines in the Metro Rail System. Opened in 1990, it is the oldest and second busiest line in the system with an estimated 26.26 million boardings per year. The proposed Regional Connector would link it to Union Station. It is operated by the Los Angeles County Metropolitan Transportation Authority.

The Blue Line passes near to the cities of Vernon, Huntington Park, Lynwood, and Carson. The famous Watts Towers can be seen from the train near 103rd Street Station.

The line runs South from 7th St/Metro Center along Flower Street turning South East onto Washington Boulevard and then South onto Long Beach East Avenue before joining the Pacific Electric four track right-of-way to Willow Station which runs as far as Long Beach where the line follows Long Beach Boulevard to its destination. There are some elevated structures just south of Downtown and a brief tunneled section in Downtown Los Angeles. It connects with the Green Line at Imperial/Wilmington station.

Rosa Louise McCauley Parks (February 4, 1913 – October 24, 2005) was an African-American civil rights activist, whom the U.S. Congress called "the first lady of civil rights", and "the mother of the freedom movement".

On December 1, 1955, in Montgomery, Alabama, Parks refused to obey bus driver James F. Blake's order that she give up her seat to make room for a white passenger. Parks' action was not the first of its kind to impact the civil rights issue. Others had taken similar steps, including Lizzie Jennings in 1854, Homer Plessy in 1892, Irene Morgan in 1946, Sarah Louise Keys in 1955, and Claudette Colvin on the same bus system nine months before Parks, but Parks' civil disobedience had the effect of sparking the Montgomery Bus Boycott.

Parks' act of defiance became an important symbol of the modern Civil Rights Movement and Parks became an international icon of resistance to racial segregation. She organized and collaborated with civil rights leaders, including boycott leader Martin Luther King, Jr., helping to launch him to national prominence in the civil rights movement.

Francis Dayle "Chick" Hearn (November 27, 1916 – August 5, 2002) was an American sportscaster. Known primarily as the long-time play-by-play announcer for the Los Angeles Lakers of the National Basketball Association, Hearn was remembered for his rapid fire, staccato broadcasting style, inventing colorful phrases such as slam dunk, air ball, and no harm, no foul that have become common basketball vernacular, and for broadcasting 3,338 consecutive Lakers games starting on November 21, 1965. Additionally, Hearn started the now common tradition of estimating the distance of shots taken.

Of note is that most of Hearn's games in the television era were simulcast on both radio and television, even after most teams chose to use different announcers for the different media.

Hearn grew up in Aurora, Illinois in west suburban Chicago and attended high school at Marmion Academy and college at Bradley University. He earned the nickname "Chick" while an Amateur Athletic Union basketball player at Bradley, when teammates played a prank on him: giving him a shoebox to see his surprised reaction when he opened it and found not sneakers inside, but instead a dead chicken.
