When most people hear 'The Iron Man' they think of the massive juggernaut of the Marvel films that fill our cinemas, or perhaps of their comic book origins. But not me. The 'Iron Man' will always be a book of that same name from my childhood, written by English author (and later Poet Laureate) Ted Hughes.

Terrified, humans send their armies to destroy the dragon, but it remains unharmed. When the Iron Man hears of this global threat, he allows himself to be disassembled and transported to Australia where he challenges the creature to a contest of strength. If the Iron Man can withstand the heat of burning fuel oil for longer than the space being can withstand the heat of the Sun, the creature must obey the Iron Man's commands forevermore; if the Iron Man melts or is afraid of melting before the space being undergoes or fears pain in the Sun, the creature has permission to devour the whole Earth. After playing the game two rounds, the dragon is so badly burned that he no longer appears physically frightening. The Iron Man by contrast has only a deformed ear-lobe to show for his pains. The alien creature admits defeat.
Ignore the sign. It's been there since the 1960s and it's a public golf course where visitors are welcome anyway. Please DO NOT place stray golf balls into the container as they interfere with the workings. I suggest you park in Mooney Street for this one, just before the steep hill to the cul-de-sac. Walking from IM2 to IM3 can be tricky otherwise.
