The exercise period under "Lock Down Rules".

As the UK tries to prevent the further spread of the corona virus, 

 citizens are allowed to exercise, outside their home, only once per day.

My route takes me across the field behind our house to a point, from which,

 I can look down on the River Tamar, across to the Naval Dockyard.

There is always something interesting to see, be it the wildlife or shipping movements.

But most important of all, I seldom encounter another person.
