4°C, full sun but ice patches remain light NE breeze

This is Cheshire lines which runs up the side of Lancashire. It looks icy but there were no problems with grip. It was a fine day and I was so glad to be out.The muddiest part is by a sewage works and though the puddles look large, the best line is straight through the middle of them. Around there should stink but now it doesn’t. That is a Covid problem – I can’t smell bad things. You’d think that was good, but actualy it’s a nuisance. How can I tell if food is off, or whether a shirt needs a wash?
