Hagrid, together with Madame Maxime, went on a quest to find giants and win them over.
"Ran inter a couple o’ mad trolls on the Polish border an’ I had a sligh’ disagreement with a vampire in a pub in Minsk, bu’ apart from tha’ couldn’t’a bin smoother."
They visited Dijon in France, had some problems with trolls at the Polish border, met a vampire in Minsk and finally arrived at the mountainous place.
"An' then we reached the place, an' we started trekkin' up through the mountains, lookin' fer signs of 'em..."
They passed the Alps, the Carpathians seemed to be off their course, there are no mountains in the vicinity of Minsk (Belarus doesn't strike as a mountainous country).
Where did they go? Are there any hints I missed in the story?
