Over and over again, I read the comment that Americans can't win on red clay because there are few clay courts in the US and that its not a significant part of the development of most American tennis players. My question is why are there so few red clay courts in the US? Is it the cost of installation and maintenance? The instant gratitude theory is an interesting one, but does that really explain why there are so few red clay courts in the US? Conversely, why are there so many clay courts in Europe and South America? Are they more willing to put up with the expense?
