Olifantenpaadjes...i saw the book some time ago while i was in Paris and it was something...fascinating.
Never heard of before but so 'regular' it stayed in mind.
Everytime i see this 'elephant-path' (desire-lines)
i wanted to know more about it.
So i found this video. You have to watch this. Sorry that it's in dutch.
Here you can find out all about it.
