Ghost swimmers at the blocks

We have had these amazing clouds sweep in today racing across the sky They have brought some squalls but mainly it's been a dry day.  I have had a head most of the day and it still hasn't gone.  I haven't had coffee for the last two days and I am just wondering if it is a caffeine withdrawal thing.  Anyhoo, I am now heading off to give the head a rest.  Even that brisk southerly at the baths couldn't clear it.   And before I go, many thanks for the lovely response to the last couple of blips.
