I grew up in a suburb of Greater Miami called Opa-Locka. It borders Carol City very closely. That was where I went to first grade and it was walking distance and I think it all might be Miami Gardens now.
My childhood best friend lived across the street from me. Her dad worked as a manager for a Dollar General for a bit. One day, he came home with 3 or 4 hula hoops for his daughters, of which there were 4. Their brother was maybe 2 and the girls were 12, 10, 8 and 5 or thereabouts. I was 14. The three youngest girls picked it up right away. My best friend and I had a more difficult time understanding waist hooping.
