Visible crew/equipment: The boom mic is visible when the first golfer hits his ball and the camera pans up. It's a long pole that is very out of place on the right side of the screen. You can even see it wobble.
Visible crew/equipment: At the golf course as the boys are describing what they are seeing, the camera shadow is visible on Bobby's left shoulder the entire shot. When we see both boys and Shane in the same scene, the shadow is now mostly on the dog.
Visible crew/equipment: At the beginning when the kids are helping Fisher put his cape on there is a shot looking at them. At the bottom of the frame is the shadow of the camera.
