Take a look at America over a century ago (1904): Only 14 percent of the homes in the U.S. had a bathtub. Only 8 percent of the homes had a telephone. A three-minute call from Denver to New York City cost only $11. There were only 8,000 cars in the U.S. and only 144 miles of paved roads. The maximum speed limit in most cities was 10 mph.
