I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
The Greensburg tornado was a large and devastating tornado that moved through Kiowa County, Kansas, on the evening of May 4, 2007, amid a tornado outbreak across the central United States, causing catastrophic damage to the town of Greensburg. The tornado tracked 28.8 miles (46.3 kilometers) through the area, killing at least eleven people and injuring sixty-three others. The tornado was the first to be rated EF5 on the enhanced Fujita scale after the retirement of the original Fujita scale in the United States in 2007. This photograph, taken for the Federal Emergency Management Agency, shows the destroyed town center of Greensburg on May 16, twelve days after the tornado struck.Photograph credit: Greg Henshall
