The thought crossed my mind. I wish I could recall when I read the article, which may have been posted here by Sean from NEIN at around the time the diver was found in the Hudson River. My thought then is it is now, is there are literally thousands of places in the Catskill Mountains where someone could stash a nuke without any fear of it ever being found unless you knew where to look.
Should probably resist, but won't:
Catskill HILLS!
I live just south of Colorado. THOSE are mountains!
