One of the nice things about having a blog nobody reads is that you can publish information in public, without anyone really getting it, except your intended targets.
So congratulations to Jennifer Korsta of Poughkeepsie NY for uncovering the hidden treasure at that place with the thing. Now Jenny, all you have to do to follow the next clue is figure out what that thing is, and where it belongs. I hope you enjoy the loot you have found already, and best of luck to you.
