My favourite part of the walk takes me through a secluded section of the greens, that is surrounded by hills. The road is only 100m away, but you can't even hear the traffic noise. You can so easily fool yourself into thinking that you're all alone on a hill in the Austrian countryside.
From there, it's so easy to forget that the greens are not maintained purely for the enjoyment of frolicking pedestrians.
And it's so easy to forget that other humans exist, apart from the obvious example of Maria von Trapp, who, at such moments, is impossible to forget...
(Maria von Trapp has a lot to answer for.)
