Smoke and Lights
A zoomed-in view of a of a building 240 meters from our apartment (according to the little camera's metadata--a quarter of a mile). It was 16:32--55 minutes before sunset on a damp, cold, cloudy day with occasional bits of rain. We stayed inside--in part because the Gilet Jaunes demonstrators had planned to pass along the Rue de Tolbiac at the top of our street. A relatively small group of them probably did; we couldn't see them from our windows, but traffic was blocked for 30-40 minutes. They were certainly very active elsewhere in Paris and France--for the 10th successive Saturday. I'm sure it won't be the last.
I'll mark the map for the rough location of the building.
