What's the Meaning of a Park

Imagination turns a fence
Into a monkey bars.
Old rusty nails? That's too bad!
And watch out for the cars!

Kids can play tag anywhere:
A parking lot, a street.
A courtyard is a stadium;
A goal line, cracked concrete.

Skinned knees may tend to multiply,
And some kids may get hit.
But only one or two a year;
You'd hardly notice it.

Kids can always get along
In hallways or on stairs.
What's the meaning of a park?
It shows that someone cares.
