helicopter friday night

On Friday night at about 1:30 am a police helicopter went up and down the creek valley about three times shining a spotlight around the top edges of the valley. At about the second time, while the helicopter was down the south end, a car started up on the bike track and drove along the track in a northerly direction. Apparently the helicopter was looking for a 'missing person', the car was irrelevant, though presumably its occupants thought they were being searched for.
