Hobos have been around since the railroad system made traveling across America possible. Itinerant workers rode the rails to where jobs were available, as best they could. Their numbers grew when unemployment did, and they developed a system leave messages for each other. Or did they? Historians know that the "hobo code" we've all read about is not what we've been told before. -via Kottke
Mrs.O lived near a main rail line in Canada and told me that hobos sometime came to their house for food and water. I suspect that her house was "tagged" so they knew someone lived there that would provide things for them.
