World's largest ice sculpture

Well it could be a cloud sculpture but (correct me if I'm wrong), I think that those really really high clouds are made of tiny ice crystals rather than water vapour so I'm claiming it's an ice sculpture (who ever heard of a vapour sculpture anyway). So that would make it an (apporximately) 5 mile long ice sculpture of one bird chasing another one.

I was running along the hills when I bumped into two other runners - one of them turned out to be my pal Stevie's ex-girlfriend (and my Pizzaland ex-colleague). She's been living in Switzerland and I've not seen her in years. On the way down I bumped into two other folk that I know (small world out there).
