Britain is a country with a park on the banks of the River Medway where old men walk their dogs

 

I've been walking the dog each morning along the bank of the River Medway at 'The Riverside Country Park' at Gillingham in North Kent and it is gratifying to find a number of other old men doing exactly the same thing and because Britain is no country for old men, I think I can say that the majority would agree with the sentiments expressed on dog walker Kevin's t-shirt.

I'm sure you can fill in the blanks.
