Heavy Frost at Loch a' Chriosg

Taken during a severe spell of frost and freezing fog. The sun had set and I spotted this lone tree while I was driving back to Inverness.

I was only out of the car for about 10 minutes but this was without a doubt the coldest I have ever felt when taking photographs!
