Summer - what's more summer than kids playing in water?
Sand - I was fascinated by the fact this sand sculpture was *ahem* anatomically correct (check under the tail!)
Stone - A lot of the gravestones can't be seen at the cemetery where hobbitmum and dad are buried. It looks like this statue on one of the graves has an ivy cloak and you can barely see the stone underneath at all.
Just Hot to go, now...
