Wrong Turn 4 (2011)

Plot hole: No one wonders what happened to all the staff and patients at that sanatorium? No police ever came there and checked the place out after 30 years? And all the patient records, furniture, etc are still there?

Visible crew/equipment: Near the beginning of the film, where the group are getting ready to go snowmobiling, Kenia and Sara start talking about Porter. During this conversation, a boom mic and pole are reflected in the window of the car directly behind Kenia. (00:13:50)

Vincent: Was this about the time of your first period?
Kenia: You're a fucking pervert, you know that?
