Does anyone have a childhood memory that doesn't involve the playground? A place to become fearless, learn to hang like a bat, and challenge your friends to see who can swing the highest. It was where you went when you wanted to meet up with your friends or when you needed a minute to yourself. It was the perfect spot to kill some time, read a book, or nurse hurt feelings. Even as an adult, merely walking into a playground takes you back to a time when everything was simple, and play was a natural part of life.
