The buzz is that the City of Los Angeles wanted to enlarge the nearby park, but the incline was too steep and the shrubbery and weeds too dense to make clearing it in the usual way ~ using men and machines ~ economically feasible. So they brought in a herd of goats.
Goats! In the middle of the city! What a fantastic idea! Good for the ecology, relatively cheap, quiet, and very, very thorough. Sometimes the bureaucrats get things right! Who'da thunk?
Here are some more pix of those cute li'l goats. (Who needs a County Fair, when you live in L.A.?)
