Thanks for the comments. We stayed with friends over new year and they've borrowed some sheep to help get the grass trimmed. The farmer who brought them around treated us to brief demo of his dogs working. It's an amazing sight to see someone precisely control the actions of sheep with a few mysterious whistles and calls to his dog(s). -Najinsky
