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.

It is warm-hearted, overfriendly; quick-witted, lavish, colorful; given to extravagant speech and gestures; its people are travelers and wanderers by nature, moving, shifting, restless; swarming in Fords, in ocean liners; craving entertainment; volatile. The schnuckle among the nations of the world.”

“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 (18561924)
