Stone Culvert under the Dava Way

We went for a walk along part of the Dava Way we haven't walked before today.  It was a nice sunny day which was welcome after days of heavy rain.  The photo was taken inside a stone culvert that ran beneath the old railway track.  It was surprisingly bone dry inside.  At one point there was a pair of Greylag geese that were circling round and round for a while.  We weren't sure if we had disturbed them or something.
