It's deju vu all over again, says the Burlington Free Press,, when sheep returned for one day only to graze on the green at the University of Vermont as they did 200 years ago. The flock of sheep were invited to call attention to the university's free, weekly historic Saturday tours which are being conducted through October. Apparently sheep were a common sight on the green in the 1800s; however, students were none too pleased with the bleating or the droppings. They built a fence to keep them out in 1837 which remained until 1874. "We always thought the fence in the old photos was there to keep the sheep in, but now we know it was to keep them out," said Jeff Wakefield, Associate Director of University Communications. The sheep contentedly grazed for about two hours. No word on whether they were invited back.
