How can it be art if it looks like it's been done by a drunk with a paintbrush?

Few things make me as peevish as being told that something is art when it blatantly is no such thing.
To me the abomination that is known as the angel of the North is just a load of scrap metal. I don't care that thousands of Geordies love it. I've never met a Geordie who has given me the slightest inkling that they have any artistic taste whatever.
I loathe those statues which now litter the sands of Morecambe Bay. And this is my point. These things are an eyesore to me. I wouldn't mind if their creators confined the exhibition of their puerile rubbish to galleries - I don't have to see them there. But to plonk them in the middle of a piece of scenery without asking everybody who might ever want go there, is plainly offensive and intrusive.
And here is the latest piece of crap to be committed in the name of so-called art.
The Zig Zag Road is a tarmac trackway that leads from the A24 to the summit of Box Hill in Surrey. From there you can look out over miles of the green and pleasant land that is the South Downs. I used to live near there many years ago and it was a good place to find some tranquility for the mind and relaxation for the eyes. In short it is a lovely spot.
But the idiot London 2012 Festival committee in partnership with the National Trust (who really should know better) commissioned a fuckwit called Richard Long to produce something to interact with the landscape there. And the result was this 328 ft long obscenity committed in long lasting and hard wearing bright white road marking paint.
How is that art? The only form of interactivity that it inspires in me is a prolonged session with a blow torch and paint scrapers.
