The owner of the hoarding, who has read the email detailing my plans, has not responded. They reside up North, whilst I live on the South coast, so they are unlikely to be at all bothered, particularly judging by the uncaredfor nature of the site.
I have spoken to the council to ensure I am not breaking any bye laws. Had my work been obscene or aggressive in nature, then they would have had certain powers, but fortunately the tame nature of my work means that is one less hurdle to clamber over.
My son, who makes documentaries, has agreed to film the event, which I have given a working title of Gorilla Gran, and I plan to be in touch with the local paper to see if they are interested in the story.
For those who may be interested in a similar undertaking, I have researched the wheatpaste adhesive I need to use on http://www.destructables.org. A simple mix of wheat flour, water and sugar. The timing couldn’t be better as I have just established that I have a glutten intolerance and have a surfeit of flour at the ready.
It all feels surprisingly normal. I wish I felt the same about my research question!
