Ry got off of the train for a moment to call his grandfather, and then get back on the train.
Things didn´t go as planned, and when the call went to the answering machine, the train took off... without Ry aboard. Now, Ry is all alone somewhere in Montana. His parents are on a Caribbean sailing trip and his grandfather has fallen in in hole and is suffering from a concussion.
He has no other option except an old driveway that he walks upon, and in this driveway he finds his salvation, Del. Del agrees to take him back to his home in Wisconsin, so they started thier road trip.
