Winter day time vapour trails

This weekend has been glorious in Canberra....bright blue skies that are that certain shade of blue during the winter months. This weather breathes hope into the end of a long winter and reminds me that there is beauty in this town. And to look into the sky and see vapour trails. Delicate whiteness streaming towards the south. 

Time, temperature or the atmosphere - whatever it is, this sky looks only this way here and now. But vapour trails are always.
