20DME ML on the 340 radial it was clear skies, I know 'cause that's where Wmk2 lives:-)
Got the Quad drone out today & video'd the muck...yuk!
You can see the murk down Sth from ground level, now I know why I left the rat race many years ago
'Tis that time of year, high pressure, cold clear nights, the Fog God goes to work:-)
