I found myself in Port Hope, Ontario visiting relatives in early 2019 and part of the conversation was about the filming of 'IT'. I wish I would have known, or remembered this, when I visited, as I would have reviewed the movie so I could visit some of the sites. The conversation flowed to other topics but they were mentioning the Gan, off and on. I asked about this and they were referring to the Ganaraska river. I thought it was very cool that 'Gan' existed where they filmed 'IT'.
