A guy driving his pick-up truck towing a horse trailer, along the highway by the Pine Ridge, Reservation, in South Dakota, sees an elderly Lakota man on the side of the road. He stops his truck and asks the old man "Grandfather, would you like a ride into town?" The elderly Lakota man said "Yes, thank you, I would". So he gets in the truck, and down the road they go. After a few minutes of idle chit-chat, the elderly Lakota man asks "Do you have anything in the trailer?" The guy says "Why yes, as a matter of fact I do". "I just got a new horse for my wife". The elderly Lakota man, chuckled and said "Good trade".
