Three Bags Full

On my way home from work last Tuesday I passed these guys working in a vineyard.  

They are called 'Wooly Weeders' and are hired by vineyards to clear the grass between the vines.  Other places use them too, like Infineon Raceway which uses them to "mow" the lawns.  

They fertilize while they work, don't use fossil fuels, and are really cute.  Except for the one who kept staring at me.  Creepy Sheepy.
