Just a suggestion on what I figured out years ago...I travel all over the country, backroads many times.
Whatever town he’s planning on stopping in, call the local fire department (non-emergency number). Most of the times they’re GREAT guys and ladies, and the fire department KNOWS EVERY SINGLE ADDRESS in their district...and are pretty cool about offers a great place to eat if you’re courteous to them.
