The worst thing in walling is...

People often comment that a cold winter must be the worst thing in walling....Not so, and until recently I'd have said that actually it was driving rain.
However over the last few weeks Trevor and I have been working on the beautiful Staffordshire moorlands and have discovered something far worse...
Midges!!!

and no, even this didn't work, even with every inch of skin showing, slathered in repellant....
