Visible crew/equipment: When the gang get out of the van when they arrive at the camp, Chris tells them that she is going to take a look around. She then opens the rear door of the van and you can faintly see a reflection of a boom mic. (00:22:15)
Visible crew/equipment: When Loco is watching the girls swing from a rope in The Barn Loft, he bends down to full with the gas can and when he looks back up she's gone. If you look closely by The Barn Loft door to bottom right there is someone moving with a blue jean leg. Jason is in dark khakis. So this is obviously crew.
