Can someone please recommend a hard core tennis camp in Southern California. My experience with a couple of camps I went to was not quite I expected - their typical day was like this: They just feed you the balls and holler "good job" for a couple of hours then set up double matches for everyone to play. It's good to meet people and socialize, but it doesn't really help improve your games. What I'm looking for is a camp that concentrate improving the techniques and correcting the mistakes, it will be drills, drills and more drills. Doing 3 hours plain ball feeding in the morning then play doubles the rest of the day is a waste of money and time. Thanks in advance.
