end August, there's a day when the sun goes down at the moment the moon goes up. I was at the beach, looking up. Those weird tubular things are the remnants of some pre-historic sand-dwelling worms: the rest of the dune comes down and the harder parts, where the worms "lived", stand up a little longer.
