I figured this was a bit more appropriate for Christmas than anything further from the tropics...I took this shot on the way to Russian class at the edge of a large pond in Southern Moscow.  The pond froze over very suddenly when the Arctic weather arrived, opening a new ice road to my destination and reducing the journey time, but most importantly starting the ice fishing season in earnest for the local drinking club!  The goal was to try and show what -28 C felt like to those who missed it....hope this helps your imaginations...Happy Holidays from Moscow!
