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.

“To the United States the Third World often takes the form of a black woman who has been made pregnant in a moment of passion and who shows up one day in the reception room on the forty-ninth floor threatening to make a scene.

“So here they are, the dog-faced soldiers, the regulars, the fifty-cents-a-day professionals riding the outposts of the nation, from Fort Reno to Fort Apache, from Sheridan to Stark. They were all the same. Men in dirty-shirt blue and only a cold page in the history books to mark their passing. But wherever they rode and whatever they fought for, that place became the United States.”
