If you are not familiar with the sport, Paddle Tennis, formally known as Platform Tennis, was founded in the 1930s in Scarsdale, NY, as an outdoor winter activity played on a slightly elevated court approximately half the size of a tennis court.  It is enclosed by very tightly strung chicken wire so that play continues when the ball bounces off the screen.  Scoring is very similar to tennis, but with only one serve. Because of the close proximity of the players, it tends to be very social. Rallies are long and sometimes amusing due to the many angles and smaller court size. It tends to be easier to learn than tennis with a shorter backswing and a lot of time at net.  Most people can pick up the game and have rallies in one or two sessions; tennis, squash and racquetball players have an obvious advantage. While there are wonderful social aspects to the game, it is also great for kids – many start playing at a very early age.
