I suppose its a bit like ice sculptures,and some of the works of art that produces, especially around competition time.
My local council do not go as far as that with its large volume of sand, when it decides to turn the town hall square into a giant sand pit for the youngster's to play in, usually during school time. but we have had the odd student or two from the local university form their own sculptures to the amusement of the kid's and adults attending the event :O)
in the dec/jan storms the sand disappeared from some of our local coves and replaced it with rocky boulders, a little sand has returned but not much. long term locals say it will all come back eventually.
Perhaps someone should send one of these people round to my friend Niecey's garden. She has a 5 tonne heap of sandy soil that her husband dug out to make his huge garden pond, and she's getting a bit fed up with it just sitting there.
Its been there 5 years, and she's getting fed up with her Hubby saying he'll get rid of it, but she says the last 'Man with a Truck' took one look at it and disappeared at a rate of knots. Personally I think she should just give up and turn it into the biggest rockery in the world.
Sad to say that some of these great exhibits have been vandalised. I hope they throw the book at the three men caught on CCTV if the police succeed in apprehending them. A hard rubbing down with some very coarse sand might make them think twice before being so stupid again. TC.
