how would you get around(navigate) once TSHTF?

I think he means he'll be using the rivers that go along those roads.

To be fair, I'll probably be using them for the first 24 hours of the event. But after that, I'll be running parallel to them. Train tracks should be pretty quiet, but when they enter a town/city, a more scenic route will be the default option.

One of the things I'm learning about is navigating by the stars. Very useful post SHTF...but only at night, on unclouded skies.
