"How you get there is depends on where you are going, from the scenario, I assume the mountain location is on the west side of the Hudson River, so staying on that side of the river would be a good idea."
Yes,I imagine the safe house around Saranac Lake, so it makes sense to make it to the "right" side of the river as soon as possible.
"Depends on where they are located and the relative distances. No one answer without geographical facts and means of transport by both parties."
A is around Saranac Lake and has a SUV. B will probably stranded on foot.
"Wait for a while, but don’t go looking."
That's my recollection to. To go looking for a specific person in such heavily populated area would be like seaching for the proverbial needle in the haystack and would reduce the chanches of survival for both.
"I think it would be helpful if you sat down and did a study of a Google map of New York State."
I'm actually doing it. I'm kind of osbessed with geography, due in part to my job, but no amount of study on a map can substitute for the actual experience of those who live in the area or know it well first hand. So I'm very grateful to all of you, please keep up with suggestions!
