It seems to always happen this way: dates for sampling tallgrass prairie coincide with the first week of Wimbledon matches which are aired during the day (when I'm on the prairie). Text messages came pouring in all week with news of the upsets-- Nadal, Federer, Tsonga, Sharapova, all grass court specialists, and all knocked out in the very early rounds. My bracket is a red streaked mess with only 59% correct on the Men's side. There's a problem at Wimbledon that isn't receiving much airtime. The Olympics took place at Wimbledon last summer, and there's a new Grounds Supervisor in charge this year. The grass is slicker than usual, which is why all of these grass specialists are slipping all over the place. Having conducted vegetation sampling on the same prairie damaged by overgrazing since 2008, I can recognize a problem with grass in this arena, just as Maria can notice problems in her grass world.
