polskikrol: Checked up on this one on a 7+ mile walk around Hoboken after work. Indeed the cache is gone and the hidey hole has increased in size from the last few years of usage. Since the hole is within view of the pathway (and most of the small rocks used to hide the cache are also gone) perhaps a muggle took it or a maintenance worker discarded it.
Archiving this one as its not prudent to rehide a new container here.
