I have not been able to go to Glen Etive and from all I've seen it seems a place to which I must go when I go back to Scotland.
Pity the chances of a weather like that repeating are slim.
Not all that slim. The weather we had during The Week has pretty much remained the same here - warm sunshine, cool breeze, very clear air. We had some rain last week, mainly overnight; I've been out shooting every day.
Scottish weather is usually pretty reliable in May/June and Sept/October; this year March was fantastic (this is unusual). The months to avoid are July and August - wet, humid, lots of midges, LOTS of tourists.
