Everytime this thing took a bend foul smelling water sloshed out of the back of it, left side then right side.
Eventually I had the chance to pull over in a layby, and in true "typical" style the lorry pulled off the road at the next junction about 300 yards away from where I had just stopped.
Had to wipe the spray off helmet / jacket etc using a piece of old rag I carry with me on the bike.
I did sontemplate trying to find the lorry and have a word, but could not be arsed, weather was too nice anyway.
Shame about your ploughmans, that would have been quite nice !!
