I've always been a tennis fan. I can remember getting up early to watch the Wimbledon or French Open finals on Sunday mornings, and then becoming "fallout" as I was then inspired to pick up a racquet and play. My oldest brother Adam was kind enough to arrange for me to get tennis lessons when I was 12 or so, and ever since I've been a decent player. Besides struggling to be consistent with my backhand, I've always found that one of the hardest parts of playing tennis was calling whether shots were in or not. Sometimes it's simply hard to tell, so in the interest of fairness I only call it out if I'm sure it is - if I just "think "it is I let the play continue. Adam does the same when we play, so I'm not at a disadvantage (at least not in that way - he usually wins so I'm losing out somewhere). If you've watched tennis on television lately, you must have noticed the HP Hawkeye thing they use now for "instant replay" that allows the players to challenge the call made by the linesperson. I think it's hilarious. After a challenge, everyone looks to the ends of the court, where giants screens show the replay. The suspense builds, and then onto the display comes an animation that shows the ball landing in relation to the line. Sometimes the call is reversed and sometimes it is confirmed, but every time the players and crowd seem satisfied that justice has been done. Somehow I think some of the players I grew up watching wouldn't have been quite so accepting of the computer generated verdict. I can picture Lendl or Connors ranting on and on about it to the umpire, or McEnroe saying something like... "You gotta be f***ing kidding me! I'm gonna lose this game because of a f***ing cartoon!"
