Lots of questions.
1/ Where did the car do the 20-30 point turn when it couldn't leave the valley via the "Myrtleford Gate" ? Does anyone know where this spot would have been. It seems like it must have been near a camp site as other campers heard the car.
2/ The car was then captured by video "on Mount Hotham" - where was this - is there a location? Is it the road near Mount Hotham that leads north, into Bright, or actually on the road going right over Mount Hotham (heading east).
3/ Did those CCTV road cameras catch the car at any other times - e.g. going IN to the valley? if so, which direction did it come from?
4/ Less important - Russel's car was locked, yet it seemed that wallets had been run through and contents scattered. Where were his keys? I assume probably burnt in the tent fire?
5/ Less important - Why do you think a car would tow a trailer like that. Just for extra supplies? But there isn't much/anything on the car's roof racks. It seems like a lot of bother to tow on those roads. Would a likely reason be to bring back deer? And what is covering the trailer - it looks like a board?
