Goats: Mother Nature's answer to weed-whacking and pesticides.
Congressional Cemetery in Southeast D.C. is 35 acres of tombstones, mausoleums and even a 20-foot-tall totem pole. There are plenty of political animals buried there, but today the partisan elephants and donkeys will be joined by about 100 goats.
The goats will be grazing on vines, poison ivy and weeds, invasive species that have been killing the many live trees that dot the cemetery. Officials say that the goats are a greener way to weed, and they even produce their own fertilizer.
The goats will be at the cemetery for 24 hours over the next six days.
