“That were for me Bohemian villages (rubbertwist)” ? According to my Oxford Duden German Dictionary. Gummibänder is rubber bands, one of my favourite German words, along with Auspuff - exhaust.I thought a fell was stony ground?
As for the German:
das waren für mich böhmische Dörfer (gummitwist)
But as I 'did' French (badly) Google was my friend..
