The_Eh_theist: With the light of what has transpired today, I will have to archive these two caches, which Seaway has now deemed to be on private property, despite no signage stating so. I will be unable to remove these caches for fear of being fined and I cannot endorse anybody going to remove them on my behalf or to find them.
I am however glad that the story had a happy ending and it reinforces the wisdom to cache with others and not alone.
