I spotted these hard working sheep on the Silverado Trail as I was driving home from work. These ruminating ovines must be the ultimate in a low emission, vineyard management programme.
This is quite a trendy practice these days. It satisfies the tree huggers and your vineyard gets fertilised at the same time.
Of course, none of this would be possible without a good Border Collie in charge of the whole operation. The Vinodogs could learn a lesson, or two, from this industrious poochie.
