Not a drop of wind, those midges must have driven you mad!
I remember being warned about them the before my first outing to some hill lochs in Perthshire and just politley nodding not paying much attention because fresh over from South Africa I thought I had been exposed to more savage creepy crawlies while fishing and survived ranging from mozzies and putsi flies to hippos and crocs.
I was wrong. Very wrong.
Had similar conditions to those in the pics with fish rising everywhere but was driven off the bank quickly with my tail between my legs by the black clouds of death.
Ended up looking like Freddy Krueger for the next few days.
