Is it freezing?

Awake and read in bed. I put sheets on plants because it was supposed to get down to 35 degrees. Then I found row cover and put it on the beds too. The mess is when Maple tree whirly gigs have dropped n the sheets and I don't know if I should wash the sheets in the washer and get those whirly gigs all over the washer. A student came to school today and started to make up missed work. We had an exit meeting for absent student. Tried to reach by phone, 4 people, no answer. At home it was windy and cold. I was happy just to stay inside. Plants need to get in the ground, so I hope tomorrow will be better. Denny and I watched Netflicks in bed. Pictures from Mexican in Madison:
