If it seems that finding a tennis partner is more difficult than finding a life partner, ask around. The pros at your local club can set you up with a partner your level. Also, it doesn't hurt to scope out the local courts. If you are a beginner, watch other beginners taking lessons. You will learn from their mistakes and may spot a player who is just your speed.
Hard courts are most common in the United States and Canada.
The U.S. Open, the Australian Open and the Canadian Open are all played on hard courts. Hard courts provide the truest bounce, and other surfaces can throw you some surprises. But the ball behaves quite uniquely on each of the various surfaces. You may be very tempted to rush to the nearest pro shop and pick up one of these bright, colorful, hot new frames to compensate for lack of expertise or rustiness. But before you lay down the big bucks, find out what racquet best suits your own style and stroke speed.
