The Red Line is an elevated train that provides 24-hour train service between Howard on the North Side and 95th/Dan Ryan on the South Side via downtown Chicago. Do not take this train day/night to or from the south side of Chicago if you are white unless you want to get beat up, jumped or raped.
New girl living on south side: "hey let's take the Red Line "L" Train up to the city"
Friend who's been living there: "yeah girl, we can take the Red Line "L" Train if you want to get raped, beat up, stabbed and have your phone and money stolen"
