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:
“When, in some obscure country town, the farmers come together to a special town meeting, to express their opinion on some subject which is vexing to the land, that, I think, is the true Congress, and the most respectable one that is ever assembled in the United States.”
—Henry David Thoreau (1817–1862)
“I feel most at home in the United States, not because it is intrinsically a more interesting country, but because no one really belongs there any more than I do. We are all there together in its wholly excellent vacuum.”
—Wyndham Lewis (1882–1957)
“... 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)
“We now in the United States have more security guards for the rich than we have police services for the poor districts. If you’re looking for personal security, far better to move to the suburbs than to pay taxes in New York.”
—John Kenneth Galbraith (b. 1908)
“The House of Lords, architecturally, is a magnificent room, and the dignity, quiet, and repose of the scene made me unwillingly acknowledge that the Senate of the United States might possibly improve its manners. Perhaps in our desire for simplicity, absence of title, or badge of office we may have thrown over too much.”
—M. E. W. Sherwood (1826–1903)
