Right now it's 1*F with 25mph wind. Tomorrow it's supposed to be 5*F with the same wind, and I have to remove and install a remote mount engine radiator on a freakin roof top. When it's 30* outside I get all the generator inside to work on, then when it turn really cold I get the outside jobs. It was cold enough when I was working outside today that my Fluke meter didn't work to well and my clamping ammeter didn't work at all.
