Smoke this morning

When I got up this morning, there was smoke in the air. Not a lot, but visibility was reduced and it did smell as though someone had had a bonfire. Some people were wearing masks, but most were going about their business as if nothing was out of the ordinary. During the day, it lifted. In the afternoon was back to clear skies. The wind direction had changed, probably. I was determined not to let my 7 Rubble mask go to waste... so I put it on for this picture.
