Ha ha, I saw that a couple days ago. What struck me was how quiet they are, aside from the noisy bells. I used to work for the range department of the US Forest Service and part of my duties included tracking the movement of several thousand head bands of sheep. You would never imagine how difficult it could be to find them! There were time I drove right by them as they grazed in the brush and didn't even see them there. It often wasn't until the guardian dogs ran out barking that I realized the sheep I was looking for were right there.
