No mention of trains?
Just #10 & #11.
Well, I suspect that Jeff Davis never jumped trains.
But a lot of real ‘hoboes’ didn’t either. They back-packed around.
I remember my Grandmother telling me about ‘hobo codes’ that itinerants would write on the sidewalks, barns, etc., letting others of their ilk know that this was a good place to get a meal - or a place to stay away from.
Did you even read the excerpt? Rules 10 and 11 both directly reference trains.
