I gave three lessons on a day that didn't get above 34. One was a putting lesson that I couldn't do in my bay (no shelter from the wind).
The worst day was the day after the ice and snow. I spent three hours with a local golf pro. He was able to come because his course was closed. The wind chill was in the single digits, but it did get into the teens. The snow was a great reflector for the sun. The Casio got some great pictures, although we both became swingers (women) because of the cold.
Yoda sent me some pictures from Hawaii, and I told him it wasn't very kind of him.
