Sheep Tunnel

Whenever I go through my photo files, seeing what I can delete, I will usually see something that catches my eye.  This little tunnel is one my dog and I go through maybe every few weeks, if we venture up to the wood at the top of the hill.  Being of average height, I have to do my Groucho Marx walk to negotiate it,the only alternative being to limbo dance, because the ceiling of the tunnel is between three and four feet high (it slopes).  Above it is a railway line.  We once returned from our walk to meet two rams guarding the entrance (of course, this was a day when i was without my camera), and we had to somehow corral them and slip past before they, or my dog, got too excited about things.
