Found it! Happy to see that the last cacher didn't forget to log it, but actually left it at 'Lang parkeren?'.
I would like to post a photo, but visited in grey weather, so nothing pretty there and the cache deserves it! Check out http://www.autotuin.dds.nl/index.html to sneak a peek at the location.
Know some friends (geocachers too) travelling to Italy in June. Will let them grab it after sharing it with B-mannetje.
I wish you a safe journey, Bikie!
