I didn't make it to Holiday Park yesterday; instead I slung my racket over my shoulder, hopped on my bike, and rode to Hardy Park, where I tested my shoulder by hitting against the wall.
A group of teens rode skateboards on the abandoned shuffleboard courts. They would glide along, jumping from one elevated panel to another. They did this over and over, never tiring of the routine. It seemed so simple and pointless until I remembered that I was repeatedly hitting a ball against a wall.
