Are you / have you advertised this in your own local newspaper, and by advertised I mean
contacted the newsdesk? Even if it's too late for the next issue it might be worth having
some photos after the event and contacting them to tell them that this is what you did
and why. Our local newspapers have all sorts of weird and wonderful things in them, and
plenty of charity-related stuff.

What does cooking 'via manifold' entail? I've never heard of that word, other than in
referring to a pump found in laboratory machinery.
