OK, it is COLD!

I always know when it gets REALLY cold, without looking at the thermometer.  When the temperature gets into the teens, frost crystals appear on the window pane when we wake up in the morning.  The crystal patterns are absolutely fascinating if you look at them closely.  So I got the camera and a macro lens so that I could do these close-ups.  Dean will like that I got REALLY close to these.  Sometimes when I do close-ups, I am not close enough for Dean!  Please click on it so you can see all the detail in the crystalline structure.
