I went to see the US Open and it was a place with a good atmosphere. The center court is, as expected, on a scale not found in the US and Japan, and the player was about the size of a rice grain when viewed from above. Even in September, it is surprisingly cold at night and the upper part is extremely cold, especially when the wind is strong, so it's best to bring a thick haori just in case.
