We get a lot of jet trails here, I’m not sure why. They show up during crisp clear winter days, especially.
This was early this morning: I went out while the kettle was boiling, and there was a plump little magpie sitting in the tree. By the time I went upstairs and fetched my camera, he had flown away, but the jet trail had showed up, so I took that instead. A woman leaving the house two doors down glared at me as I went back inside with my camera, mistrusting my motives.
