The game required you were
1) a kid
2) at a minor league baseball game
3) bored (see #1)
4) able to get away from where your parents
a group of kids would meet up, none of us knowing each other
before that night, crush one of those wax covered cups
and use it like it was a ball and hit it with your hand and
run around the makeshift base path.
That's what we called fun in Richmond, Virginia when I was your age.
