During the early 1920s, the authorities of Miami allowed gambling and were very lax in regulating prohibition, so thousands of people migrated from the northern United States to the Miami region.
Počas dvadsiatych rokov úrady Miami povolili hazardné hry a boli laxné v regulácii zákazov, preto sem migrovalo veľa ľudí zo severu Spojených štátov.
