In the end, its two A-holes filming themselves committing an act of vandalism. Rather like those idiots who record themselves doing 120mph, put it up on Youtube and then wonder why the police come knocking. Okay, just a Sycamore but a living tree nonetheless and famous around the world. Until two brain-dead members of the species decided otherwise (hope they get a bit of porridge). I see guys spraying the walls and fences of the Railway Path I use here in Bristol. They sometimes spray the asphalt itself. Its nice to see some old stone railway bridge abutments coated in moss etc....but then you get some awful tag in silver sprayed all over it...bit like dogs peeing on lamp posts etc, isn't it?. I've often wished I could trace those responsible and sneak out in the wee hours to spray their front door, just to see how they like my 'art'.
