Leptoceratops: I decided to archive this cache. Things have changed and it seems like visitors are not warmly welcome here and therefore it is not a good place for geocache. Probably someone could arrange last visit to the place for example owner and collect with intention not to leave it in nature.
I hope that those who found this cache enjoyed their visit.
I will mark this territory as restricted and won't publish new caches until fences are opened to all public 24/7.
