Another bitterly cold but sunny day so decided to do a quick ride around the area and be home for lunch. Tried to stick to the main roads but because I was on my mountain bike I wanted to go along some of the “less well used” roads. This was fine to a point but going down hill on one particular road I came to a point where it was just a sheet of ice which forced me to get off the bike and walk down the hill very carefully, some minor slippage but I made it to the bottom in one piece. I decided to stick to the main roads after that until I got home.
