I am transported back to the elementary school playground. Hour upon hour we played 4-square on that black top. Except on icy days when inch-thick plates of ice prevented access. On those days, with the heel of my snow boots, I pounded and pounded until a few inches and then a few more gave way. Others join in the assault. Occasionally, a large sheet gives way and a shout of triumph rings out.
The school bell sounds. Man, that was a lot of work!
Next recess, we play.
