In the orthodox and structured world of Alberta fly fishing, by mid-summer the days of wine and wildroses, should have been long past.That cosmic interlude when big, reclusive brown trout leave their lairs on West Country trout streams and blatantly gorge on surface insects. Sometimes in the bright light of day. What I’m describing is that mercurial time in May and June which is sometimes known as Fly Fishers’ Christmas because often you don’t know which present to open next.
