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 white American man makes the white American woman maybe not superfluous but just a little kind of decoration. Not really important to turning around the wheels of the state. Well the black American woman has never been able to feel that way. No black American man at any time in our history in the United States has been able to feel that he didn’t need that black woman right against him, shoulder to shoulder—in that cotton field, on the auction block, in the ghetto, wherever.”
—Maya Angelou (b. 1928)
“You are, I am sure, aware that genuine popular support in the United States is required to carry out any Government policy, foreign or domestic. The American people make up their own minds and no governmental action can change it.”
—Franklin D. Roosevelt (1882–1945)
“I thought it altogether proper that I should take a brief furlough from official duties at Washington to mingle with you here to-day as a comrade, because every President of the United States must realize that the strength of the Government, its defence in war, the army that is to muster under its banner when our Nation is assailed, is to be found here in the masses of our people.”
—Benjamin Harrison (1833–1901)
“The professional celebrity, male and female, is the crowning result of the star system of a society that makes a fetish of competition. In America, this system is carried to the point where a man who can knock a small white ball into a series of holes in the ground with more efficiency than anyone else thereby gains social access to the President of the United States.”
—C. Wright Mills (1916–1962)
“Because of these convictions, I made a personal decision in the 1964 Presidential campaign to make education a fundamental issue and to put it high on the nation’s agenda. I proposed to act on my belief that regardless of a family’s financial condition, education should be available to every child in the United States—as much education as he could absorb.”
—Lyndon Baines Johnson (1908–1973)
