Maceo-Dickinson line

The expression Maceo-Dickinson line was used in Texas in the early/mid 20th century referring to the Galveston County line where it met Harris County.

The expression was a pun which made reference to the Mason-Dixon line. From the 1920s to the 1950s the Maceo crime syndicate controlled Galveston, Texas and established a gambling empire there that ran through much of the county, including casinos in Dickinson, Texas. The county had a notoriously lax law enforcement environment which represented a sharp contrast with neighboring counties, particularly in the later years.
