Indeed it is. I sort of imagined they'd blow away. Pretty funny to arrive and find your last year's sculpture still standing .

Yes it is much stronger than most people think. I use sharp sand which locks together when conpacted.

I think they may still have one of mine in China which I made in 2002. But I don't count that. They sprayed it with so kind of weird varnish to preserve it. It's a pity because it was a disaster of a sculpture. I must make a post about that one.
