I was down at the beach today. It was warm and sunny but with fog at either sides and along the horizon. The extra is put in because I saw this white streak and thought for a minute it might have been the International Space Station! Bear with me, I had seen that it was visible the next couple of days. However I did realise that surely that would be at night and also wouldnt be in the same place as this thing was although it did disappear and kept coming back. Turns out it was the tip of a windmill. I hadn't noticed that all the windmills were covered up with the fog!
