In reply to Derry:
It's quite something, Derek. I doubt you'll be disappointed. And Marti's talking about making it even better. (I think he was really impressed with my suggestion of lining it with garden gnomes.)
Last Friday, after we'd all been rained off (yet again) I finally plucked up the courage to ask him how on earth he'd conceived it. He looked at me witheringly and said, "Well, I'm practical..."
Ouch!! Still think he's impressed with the garden gnome idea.
