My Stepmom watches and LOVES the Curse of Oak Island.
I tell her its carp, and they have not and will not find anything at this point, but she does not care.
I mentioned if they had found treasure, it would be on CNN, on the local news, and every news paper long before an episode of the show revealed it. that thought had not occurred to her.
As a kid, I loved "In Search Of", and shows like it. Bigfoot, UFOS, Loch Ness Monster, etc.... all seemed possible to a 7 year old. But now, in the age of smart phones, remote game trail cameras, thermal FLIR type cameras on drones? If there was a bigfoot, or aliens, or Nessie, someone would have legit evidence by now.
