How about some sort of communal get-together at a local hostelry following the final GdS event of the year?
It would mark the end of a season of great effort and reward..............
You could, sort of, er, present badges, make a speech, drink beer.
Mind you some of the early finishers might have to wait awhile for the lanterne rouge to arrive.............
Maybe a pub near Chailey?
Or perhaps keep the village hall for an hour or two longer and have some sort of do? Maybe get in a barrel of Harveys? I could suggest an outside caterer who might be prepared to help...........
Just an idea to add to the burdens of your life, Mr Zoom. Others would help with the organising........
