GafferGamgee: Unbelievable. After Ger Grylls's log I checked and it is indeed gone again. There wasn't a soul in the park when I replaced this yesterday, I can only think I may have been spotted from the window of an apartment overlooking the park. It couldn't possible have been spotted by a random passer by. Anyway...regrettably, time to archive. It may return in another guise sometime...
