The temperature yesterday was a record high. It was 84F. A major winter cold front is coming in today, so by tomorrow morning the temperature will be in the 40s F. I think the photo shows wind sailing, but I am not sure if that's the right name. They are on Lake Ray Hubbard any time there is a wind. I think yesterday may be the last time they are on the lake for a while.
There are a couple of extra pictures on my second page.
