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:
“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)
“Fortunately, the time has long passed when people liked to regard the United States as some kind of melting pot, taking men and women from every part of the world and converting them into standardized, homogenized Americans. We are, I think, much more mature and wise today. Just as we welcome a world of diversity, so we glory in an America of diversity—an America all the richer for the many different and distinctive strands of which it is woven.”
—Hubert H. Humphrey (1911–1978)
“What the United States does best is to understand itself. What it does worst is understand others.”
—Carlos Fuentes (b. 1928)
“In the United States all business not transacted over the telephone is accomplished in conjunction with alcohol or food, often under conditions of advanced intoxication. This is a fact of the utmost importance for the visitor of limited funds ... for it means that the most expensive restaurants are, with rare exceptions, the worst.”
—John Kenneth Galbraith (b. 1908)
“Printer, philosopher, scientist, author and patriot, impeccable husband and citizen, why isn’t he an archetype? Pioneers, Oh Pioneers! Benjamin was one of the greatest pioneers of the United States. Yet we just can’t do with him. What’s wrong with him then? Or what’s wrong with us?”
—D.H. (David Herbert)
