Horseheads is technically southern tier ny not finger lakes. I wish I had some good info on the area, there's the military barge in the middle of Seneca lake that's pretty secretive. Also old salt mines. Really no signs of activity going on from the surface that i know of in those tunnels but have heard rumors they go under Seneca lake. Plenty of mil helicopter traffic that doesn't show on the radar sites. And of course lots of extremely expensive lake front properties going around all those miles of lakes. Some celebrities have property there john Travolta comes to mind
