Wimbledon is one of four Grand Slam tennis tournaments, and is the oldest and most prestigious tennis tournament in the world. Held at the All England Club in the London suburb of Wimbledon since 1877, the tournament has also become known for its infamous rain delays. Wimbledon participants and viewers have grown to expect unpredictable weather, ranging from torrential downpours to on-again-off-again trickles. But beginning this year, the rain will no longer be a factor in game play.

When Wimbledon kicks off Monday, spectators will find a new waterproof feature on the Centre Court - a translucent retractable roof. Dedicated last month in front of crowd of nearly 15,000, many believe it was a long time coming. Others are sad to see the end of an era and a long-standing tradition. The outer courts will still be open to the elements, but it won't be the same with Centre Court fully protected.

Prior to the roof, grass-protecting tarpaulins needed to be deployed by teams of groundsmen at the slightest hint of rain, and then quickly removed when the rain ended. With the unpredictable nature of the rain in England, this start-stop process could go on and on and on.
