Wow! That must have been unbelievably awful especially if you were caught outdoors and without an umbrella. Yuck!

1985 The Supreme Court of Canada ruled that almost all laws in Manitoba were constitutionally invalid because they were in English only, however, they would remain in effect until translation into French had been completed

I can just see the hustle to get that done in time.
