1996 was the first time I noticed the strange linear clouds drifting across the Winnipeg skyline. I was driving and listening to talk radio when another listener called in and asked the host “what are the long white trails over the city”? I called too and joked it was a case for X-files. Afterward I never gave them much thought and if I noticed them I supposed them to be caused by natural phenomenon such as weather fronts and wind patterns. That was until the September long weekend in 2010.
