Goat Mower - minor tongue action
Congressional Cemetery in Southeast DC recently hired a herd of goats to chomp down on ivies and other vines. The undergrowth had made a section of the property inaccessible to landscapers who needed to trim and remove trees which are potential hazards. Goats are an effective and chemical-free way to accomplish this. They were also a lot of fun to watch and drew many spectators during their week-long stay.
(and, because you may be wondering, the goats were NOT wandering among the graves and monuments; they were in a section of cemetery property not used for interments.)
