Lachwurzn: Almost 10 years are enough for a cache. Even more so as in recent years, it has been found almost exclusively by "listing-cachers" who did not care at all for solving the mystery, but just handled it as a traditional cache having received the final coordinates from somebody else or a database.
As this is already "the norm" in today's Geocaching, I will archive this one and never ever create a mystery again.
Sorry to all the mystie lovers, but you are a minority today...
