I remember that outbreak - I didn't know that it hit Canada, though (in the US, our weather maps are often gray north of the border - no weather in Canada!). Scary! I'm sure there wasn't much warning, either.
I grew up in Oklahoma and my father is a research meteorologist who studies severe storms. Ironically, we were all in State College, Pennsylvania at a meteorology conference when that outbreak happened! There was terrible damage and loss of life across the region - it makes me thankful for the better warning systems we have today.
National team trials for orienteering were in Barrie that weekend. What I remember the most was the sheet metal from a roof of a building on the west side of hwy400 wrapped around the willow trees adjacent to the old race track on the east side of the hwy. THe odd chackpoint had to be relocated by the vetters apparently as they blew away.
I also remember racing totally shitty-like and not being selected to the team for WOC in Oz. Crikey.
Hammer, what map were those races on? Mansfield? I have a slight memory of my dad and I driving up to races just after the tornado.
