OT - Why America Is Great (From the tencap tennis website) Interesting Facts About Tennis Balls 300 million tennis balls are manufactured each year. US Open: There are 60,000 Wilson tennis balls used during the US Open and they are donated for community/youth programs. Wimbledon: The 36,000 tennis balls used at Wimbledon are used afterwards as homes for Harvest Mice http://www.bbc.co.uk/news/10221571 (check out the pics!) Australian Open: Wilson supplies more than 4,000 dozen tennis balls for use during the Australian Open. Used balls are sold on site. In America, despite being a bunch of greedy bastards, we find ways to donate to those less fortunate. In England, their primary concern is field mice, and in Australia, they try to get their greedy hands on as much $$$ as possible. Not to mention, the US Open is the ONLY Grand Slam event that guarantees equal prize money to men and women.
