Somehow while reading articles linked in Resignation Anon's list, I ended up in California looking at USG documents on mining operations in California while thinking that mines could also be considered caves. (Did you know there are gold and silver mines in Napa? Yeah, me neither.) One of the operations listed was PW Gillibrand which of course led me on another chase. PW Gillibrand has an entire portion of their site dedicated to movie locations…Hmmm.
So rather than follow the wives, I followed the husband. Kirsten G and her husband got married in 2001. Her new Father in Law was directly involved with the 9/11 cleanup and 'gifted' her and her husband with close to $500,000 in 2015. Interesting article about demolition at the WTC site - not sure of the authenticity of the information, but it makes a good read. Stengel, the Time guy who bought the Gillibrand house on the Hudson is another interesting character….but that's another story.
