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:
“Prior to the meeting, there was a prayer. In general, in the United States there was always praying.”
—Friedrich Dürrenmatt (1921–1990)
“The boys dressed themselves, hid their accoutrements, and went off grieving that there were no outlaws any more, and wondering what modern civilization could claim to have done to compensate for their loss. They said they would rather be outlaws a year in Sherwood Forest than President of the United States forever.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“... while one-half of the people of the United States are robbed of their inherent right of personal representation in this freest country on the face of the globe, it is idle for us to expect that the men who thus rob women will not rob each other as individuals, corporations and Government.”
—Susan B. Anthony (1820–1906)
“The city of Washington is in some respects self-contained, and it is easy there to forget what the rest of the United States is thinking about. I count it a fortunate circumstance that almost all the windows of the White House and its offices open upon unoccupied spaces that stretch to the banks of the Potomac ... and that as I sit there I can constantly forget Washington and remember the United States.”
—Woodrow Wilson (1856–1924)
“What makes the United States government, on the whole, more tolerable—I mean for us lucky white men—is the fact that there is so much less of government with us.... But in Canada you are reminded of the government every day. It parades itself before you. It is not content to be the servant, but will be the master; and every day it goes out to the Plains of Abraham or to the Champs de Mars and exhibits itself and toots.”
—Henry David Thoreau (1817–1862)
