The Grindley

This is me, the current holder of "the Grindley" a center parks medal that a guy at our squash club won when he was there on holiday.
He was bragging about winning it in a squash tournament there and promptly lost it when someone at the club challenged him to a game for it.
It's been passed around a bit and I'm the current holder. There have been rumours that some foolhardy
souls are planning on challenging me. I'm not worried...
