I've just seen this movie this morning. Very cool guy.
Not underlined in the words: the guy and his friends in the movie have begun ride and dig the trials in the '98s. 'Fun' fact, that their trails are not legalised yet due to difficulties of the official rout, but the ones on the austrian side, which were built way later only in the recent years, are legal. This describes well, that here in Hungary one of the best thing is that if you have luck, you can ride almost anywhere and nobody* will stop you unless you behave like a d__k. But sometimes forestry will stop acting like these guys, sometimes they don't, depending on the actual office. Like a fortune-wheel.
*Ok, now-and-then a farmer or a hunter may ask what you're doing, but basicaly they are only pretending and not really having the rights they think they have. Of course, there are areas and trails restricted, but these are rare.
