A family was visiting an Indian reservation when they happen upon an old tribesman laying face down in the middle of the road with his ear pressed firmly against the blacktop. The father of the family asked the old tribesman what he was doing.
The tribesman began to speak… “woman, late thirties, three kids, one barking dog in late model, Four door station wagon, traveling at 65 mph”
“That’s amazing” exclaimed the father. “You can tell all of that by just listening to the ground”?
“No”, said the old tribesman. “They just ran over me five minutes ago!”
