I'm through episode 7. Like the show, but I agree, the lake it was shot at doesn't look the same at all, including shorelines and docks. (I don't think I've ever seen a dock at LOTO like the dock at the Bird's house).
The show does go over the top with making the locals look like something out of Deliverance. I'm not a local, but 99% of the locals I've met are just as ordinary as me, just with a much stronger accent
The Blue Cat Lodge in the show reminds me of what some places were like back in the 1980's...The Clown and Ozark BBQ come to mind.
Glad it was renewed for another season.
