My shop is too big and drafty for my 6 ton central heat to keep up. I worked on Murray yesterday and with the heat blasting for hours it got all the way to 51 degrees! Last year I had to hang a big canvas dropcloth and cut the room in half to get the heat up. That is my plan for today. In the morning I bought a wrapped up sandwich at the grocery store and left it in the truck for lunch and when I went to get it a couple of hours later, swear to God it was frozen. But, to balance out pain and pleasure, Jan and I watched a pair of bald eagles from our living room windows. They were gliding back and forth for about 10 minutes. They like it cold.
