On the news conference I heard that Kati Kim told her rescuers that she thought that James had taken the strobe flash from the camera with him.
That would surely get noticed by someone with night vision capabilities who is participating in the search.
Hoping he is found soon.
But burning tires at night in the dark......not the smartest. If he's using the strobe light in the daytime....not smart either.
It would seem these people were in way over their head. Travelling to a remote area with small children in the winter. Sheesh.
