Yes, that's part of living in Montana!  We must endure these stretches of below zero temperatures.  They generally don't last long.  We know there is light at the end of the tunnel.  It just makes for a lot more work keeping things watered, troughs heated so the animals can get a drink and making sure they all have enough bedding and feed.  So far milking goats in these temps hasn't been too bad.  Warm wash water, warm udders.  Only my pinkies get cold.  As long as the wind doesn't blow, we are in pretty good shape.  Oh yes, and the power stays on!  We woke Tuesday morning to no power.  That's generally not much of a problem around here with the wood cook stove.  It heats the whole house.  We also have a small propane fired stove out in the family room that will run without electricity, so it was going.  I worry about pipes freezing, but the crawl space only got down to 44 degrees with it 25 below outside.  With no power, the water pump doesn't run and hence no water.  There was enough in the lines to give the chickens a drink and I could've made coffee on the wood stove, but I just heated up a cup of yesterday's that was left in the pot. 

Well, it is the end of January and it is Montana.  Our Canadian friends like to send us a blast of their cold air periodically and with the full moon and clear skies, it has been a cold one!
