Believe it or not but this fence has kept both sheep and cows out of the stream which runs own the side of our house ever since we have lived here - 16 years now. It also keeps them out of our garden which is good as my sheep/cow wrangling days are coming to an end! I have a feeling that after this winter some new posts will be needed in a few places. Fortunately we shall only have sheep as neighbours for quite some time and all they ever want to do is scratch an itch!
