Well, the rain stopped long enough today for the sky to clear .. and for the tennis courts at Jefferson Park to dry out.
So when the text messages from my tennis group came in asking who could play, I jumped at it. We had 52 °F/ 11 °C, which is still OK to play in. Temperatures down to around 45 °F/ 7 °C are increasingly dicey, and 40 °F/ 4 °C is a hard no for me.
