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 United States themselves are essentially the greatest poem.”
—Walt Whitman (1819–1892)
“... when we shall have our amendment to the Constitution of the United States, everyone will think it was always so, just exactly as many young people believe that all the privileges, all the freedom, all the enjoyments which woman now possesses were always hers. They have no idea of how every single inch of ground that she stands upon to-day has been gained by the hard work of some little handful of women of the past.”
—Susan B. Anthony (1820–1906)
“Some time ago a publisher told me that there are four kinds of books that seldom, if ever, lose money in the United States—first, murder stories; secondly, novels in which the heroine is forcibly overcome by the hero; thirdly, volumes on spiritualism, occultism and other such claptrap, and fourthly, books on Lincoln.”
—H.L. (Henry Lewis)
“In a moment when criticism shows a singular dearth of direction every man has to be a law unto himself in matters of theatre, writing, and painting. While the American Mercury and the new Ford continue to spread a thin varnish of Ritz over the whole United States there is a certain virtue in being unfashionable.”
—John Dos Passos (1896–1970)
“America—rather, the United States—seems to me to be the Jew among the nations. It is resourceful, adaptable, maligned, envied, feared, imposed upon. It is warm-hearted, overfriendly; quick-witted, lavish, colorful; given to extravagant speech and gestures; its people are travelers and wanderers by nature, moving, shifting, restless; swarming in Fords, in ocean liners; craving entertainment; volatile. The schnuckle among the nations of the world.”
—Edna Ferber (1887–1968)
