Yes, I turned the furnace on. But I had a good reason. Turns out that my fridge is on the fritz, and I really didn't want to have the fridge and the furnace on the fritz at the same time, so I had to turn on the heat to make sure the furnace was working properly. And now that I've turned it on ... I might as well leave it on.
Put in a service call on the fridge - the earliest appointment I could get is next Thursday. I'll be in Vegas next Thursday, so I scheduled at the earliest convenient time for me - Halloween. Good thing I have two mini fridges floating around the house. But going out to the porch to get my milk and my OJ will get old mighty fast.
