Anyone for Tennis ?

Although I'm not great at playing tennis, I do enjoy playing it very much. Tennis is not a very popular sport here in China, but there are some great Tennis facilities only a few minutes drive from where I live. I think you have to know someone who knows someone etc...to actually get in and play there...so i think I'm quite lucky to get the chance to have a hit. I really thought I would be very sore the next day or two after, but suprisingly, pulled up ok. The actual Tennis courts we went to are fantastic. Many Australian clubs would dearly love such an amazing set of courts to play on...some courts under cover, some outside in full sun and also practice areas to hone your skills! Seeing as many Chinese people seem to have little idea about Tennis, it seems rather odd that these facilities are here...I have to wonder how much they actually get used???
