Lugiaa: Due to lack of time and the great distance, I have to archive the geocache after 4 and half years since it was published. I was quite nearby a month ago on the way to Budapest, but it was not me driving the car, so there was no way to exit the highway and drive several extra kilometers just to get to this geocache which was about 100 m from the highway.
Anyway, the place is free now. It would be best if someone local organized a CITO event there, as it seems that the place got extremely polluted by trash. If someone finds the lost geocache somewhere among the trash, let me know and maybe there will be some kind of resurrection.
