This episode was filmed at the Gaither Planation in Covington, GA. It is rumored to be haunted and Paul said once “Recently we were filming on a real plantation – it was creepy as there was a lot of dark history. After slavery was abolished, the owner of that plantation was the first guy to be hung because he lynched all his slaves instead of setting them free. So he was hanged and now the place is historically, famously listed as one of the most haunted places in the US. “We filmed there at night time and it was just really weird and creepy. All of the graves were there, about 150 of them. It was very bizarre. I’m very practical and don’t believe in the paranormal but I do believe your imagination is a powerful thing and everyone on set got very jumpy.
I personally went on a ghost tour there and Paul was 100% right about the place.
