How much was a gallon of gas in 1971?
Gasoline dropped below 30 cents a gallon for regular gas on Dec. 28, 1971, as an on-again, off-again price war flared in Columbus. In today's money, that bargain-basement price of 29.9 cents a gallon would be equal to $1.70 a gallon, much less than the current price at the pump.

How big is the Great Canyon?
The Grand Canyon is indeed a very big hole in the ground. It is 277 miles (446 km) long, up to 18 miles (29 km) wide and more than a mile (6,000 feet / 1,800 meters) deep. It is the result of constant erosion by the Colorado River over millions of years.

Is it legal to lie on the news?
The Media Can Legally Lie. In February 2003, a Florida Court of Appeals unanimously agreed with an assertion by FOX News that there is no rule against distorting or falsifying the news in the United States.
