Okay.
So there is this part in the story:

He starred the second entry-'All that you love will be carried away (WALTON NEB)'-and
drew a line two inches above the bottom of the page, and wrote.*

*'To read this you must also look at the exit ramp from the Walton Rest Area back to
highway, i.e. at departing transients.'
Does anyone know what's there???
