Yourself too Thomas. I see by gkrellm that we may have a slow thaw, its 
up to 0.6C, at the airport 16 miles northeast and I may be able to put 
the finishing cuts on a back box panel that will bring my bigger milling 
machine back to life eventually. Not a lot of heat in that building with 
its small machines though. Just enough to keep the machinery above the 
dew point and major rusting, but not enough to keep my diabetic feet 
warm. One of the hazards of the ultimate revenge, outliveing ones last 
enemy by a decade+. ;-)
