On to the next ol’ son 

A saying of the rich country guys, going between one fun and cool idea to the next. Printed on the back of an awesome work rig; a rich guy probably just sold to another younger, but still rich guy.

On to the next ol’ son is printed on the back of a favorite vehicle, black, military grade painted, dual tired, lifted, flat bed, dark tint bullet proof windows, slight chrome trim, thieves would be afraid to break in, probably with a few gun racks, Cummings diesel engine truck, with a stabbing wagon (mid sized camper) behind it. The original owner sold it to pay for his newer, stronger truck, with a bigger, and fancier stabbing wagon (long finished horse trailer), higher military grade body, getting offers from Uncle Sams’ proudest, and with larger guns. Which he will add On to the next Ol’ son when he sells it.
