I do think that here in the U.S. we should suppose clay tennis more. Why the US has such a dislike for clay now I will never know. We used to have more clay court Tournaments. But now they are almost 100% gone! And yet then when a clay court Tournament is in full swing in Europe or elsewhere some Americans stupidly wonder why Americans can't play on clay
Also without a lot of strong top tennis players in the U.S. tennis has lost a lot of popularity in the U.S.
