"They are members of the 38TH STREET GANG."
This opening description in the play is just as important as any dialogue in the play because it shows how intricate being a part of the gang is to the characters' identity. It shows without the characters saying it the level of loyalty they feel to their gang and their neighborhood. There are several 38th streets in LA and it's surrounding areas so we googled the gang name to find out the street is actually in Vernon. Geographically, this also represents a move into South Central unlike Revolt which took place more in East LA.
