and 30 mins later I am lost looking at Hungarian villages for some reason...
Hungarian villages are fascinating. Are you tuning into something, in particular, about them? (For me, its the village sun alignments/road-parallelism that fascinates..)
I was following the Austrian border, in places it is hilariously convoluted, assuming it follows meandering rivers - the effect on fields and contrast to straight villages is fun...
