I have to laugh.
In the late ‘70’s, Chapel Hill High School, Durham Academy, and Jordan High School students had raging parties - many in/near Bahama (several hosted by a student with the last name of Hill - think UNC royalty). We also had raging parties in western parts of Durham County and Hope Valley and Orange County.
Some of these were incredibly well-organized: (1) pastures to park cars; $3/car; (2) pop your trunk to make sure no one was sneaking in; (3) $X a cup; lose your cup, buy a new one; even if you didn’t drink, you had to buy a cup; 4) $X to “access” a bong
It was Chapel Hill and the well-off parts of Durham. Parents were ALWAYS out of town. Rotating parties.
Lots of empty land north of Chapel Hill and South of I-85 back in the ‘70’s.
