When not checking out Falcon handlers or confident foxes, I like to pop on my dog walking jacket - which makes me resemble a stocky rainwater tank in a sleeping bag - sip my second coffee out on our balcony and enjoy the view of the distant Jura, the sky and the city.
It was mid-afternoon and the sun was already starting to set when these pictures were taken, but the new winter snow was still visible on top of the mountains.
However I realised that the sky has a lot of vapor trails in it.
Facing towards Saleve, I counted over ten separate trails created by planes flying over us, coming in to land or departing.
These white lines in the sky made me realise just how much air traffic Europe has and how Switzerland, being a fairly small splodge in the middle of the continent, sees a lot of planes passing overhead.
The following morning it dawned blue, cold and crisp and, when out walking with Milly, I counted fifteen different trails leaving lines on the sky. I once read that at any given time there is around 260,000 people up there; or the entire population of Orlando, Florida.
That's a lot of rock-hard bread rolls, miniscule bottles of water and sugar sachets.....
