Every Spring the city of Benicia hires out this gentleman to bring in his herd of goats and use them as all-natural lawn mowers. I took this picture of the goats from my backyard just before heading off to school. It was funny to watch them jump all over the branches of those trees.
This is a brilliant idea. Not only do they help prevent grass fires and keep the hills nice, but people love to bring their kids and watch them as they eat.
