United States
In U.S. high school track and field, boys typically throw a discus weighing 1.6 kg (3 lb 9 oz) and the girls throw the 1 kg (2.2 lb) women's discus. Under USATF Youth rules, boys throw the 1 kg discus between the ages of 11-14, and transition to the 1.6 kg discus as 15-18 year olds. Girls throw the 1 kg discus as 11-18 year olds.
Under US high school rules, if a discus hits the surrounding safety cage and is deflected into the sector, it is ruled a foul. In contrast, under IAAF, WMA, NCAA and USATF rules, it is ruled a legal throw. Additionally, under US high school rules, distances thrown are rounded down to the nearest whole inch, rather than the nearest centimetre.
US high school rules allow the use of a solid rubber discus; it is cheaper and easier to learn to throw (due to its more equal distribution of weight, as opposed to the heavy rim weight of the metal rim/core discus), but less durable.

Famous quotes related to united states:
“The men the American people admire most extravagantly are the most daring liars; the men they detest most violently are those who try to tell them the truth. A Galileo could no more be elected President of the United States than he could be elected Pope of Rome. Both posts are reserved for men favored by God with an extraordinary genius for swathing the bitter facts of life in bandages of soft illusion.”
—H.L. (Henry Lewis)
“The United States is unusual among the industrial democracies in the rigidity of the system of ideological control—’indoctrination’ we might say—exercised through the mass media.”
—Noam Chomsky (b. 1928)
“Why doesn’t the United States take over the monarchy and unite with England? England does have important assets. Naturally the longer you wait, the more they will dwindle. At least you could use it for a summer resort instead of Maine.”
—W.H. (Wystan Hugh)
“United States! the ages plead,—
Present and Past in under-song,—
Go put your creed into your deed,—
Nor speak with double tongue.”
—Ralph Waldo Emerson (1803–1882)
“An alliance is like a chain. It is not made stronger by adding weak links to it. A great power like the United States gains no advantage and it loses prestige by offering, indeed peddling, its alliances to all and sundry. An alliance should be hard diplomatic currency, valuable and hard to get, and not inflationary paper from the mimeograph machine in the State Department.”
—Walter Lippmann (1889–1974)
