Climb every moutain

You can't turn your back for a minute, can you ?

We spend a few days in Spain and when we come back, what do we find ?  Lorries and diggers on the beach shifting sand about. 

We have seen this before at this time of the year, just before the main holiday season, as when our grandchildren came to France for a Whitsun break a few years ago they had great fun running up and down the giant sandcastles.
