Continuity mistake: After Kelly's party Jason gets to his home and his dad yells him about fighting then gets to the garage and drops just some magazines and rips out the Bruce lee's poster but in the open view you can see several things on the floor.
Visible crew/equipment: When Jason and RJ get to the abandoned house and drink some cokes a boom mic is seen at the top of the screen.
Continuity mistake: When Scott is using the hose he is sitting on a chair with his house in the background. In the next shot the house is gone and there are some trees. The his dad yells at him and the house is back again.
Suggested correction: You probably hadn't a chance to rewatch carefully. The camera angle changed more or less from Dad's perspective a bit raised, and so you don't see the house but the lawn. All the green in those shots is not trees but rather the lawn, with the same shadows (more or less, the light does not quite match but it's very minor) you see previously.
