It is a tragedy. One of the sad parts of how areas were settled, along coasts, rivers and flood plains as boats were the mode of transportation for so many for so long. Not to mention flood plains being covered by such nice soil and grass - easy to put to the plow as there were no trees.
But people forget that these areas do flood, and while in Canada, or western Canada anyway that means that they have only been settled for maybe 2 to 300 years by European settlers and that seems like a long time, compared to the age of the earth it is the blink of an eye and water events like this are actually common if you look at it over say a 10,000 year time frame.
Still I can't imagine what it feels like to be forced away from your home, what you are going to face when you return and the damage to property and people's lives.
And now we get to add cars from Calgary that may be flood damaged to cars coming out of the US from places like Florida and Atlanta so beware of deals in the near future......
