In reply to Michael Griffith:
We were up in the area just over a week ago for about 5 days - we hardly saw a midge, mostly because the wind was up. However it has been unusually dry up there and the bogs were drying out something the midgies don't like. The few times the wind went down in the evening they did pop up though in limited numbers but as this was only for at most 30 seconds at a time its hard to say how bad they'd have got.
