One approves.<quoted text>LOL!! Nah- doesn't have to be that cold.
One of the things that impresses me most about parts of Canada is their concern for the welfare and safety of wildlife.
"Banff, Alberta - This Parks Canada shot of an elusive lynx was taken in March 2012, by a motion-sensitive camera at the Redearth Creek wildlife overpass in Banff National Park. The overpass enables wildlife to safely cross above the Trans-Canada Highway.
Head west on the Trans-Canada Highway from the town of Banff and before you reach Lake Louise youll drive under two unusual tree-covered overpasses. They are 50 metres wide, cost over a million dollars each, and are here solely for use by the parks wildlife. Here's a great series of Banff wildlife overpass shots, which were published on TheGlobeAndMail.com in December 2011.
Overpasses, a 2.4-metre tall highway fence and 22 underpasses have reduced wildlife road kill and collisions by more than 80 per cent. The overpasses are designed so animals cannot see the highway when crossing. Elk, moose, wolves, deer and grizzly bear tend to use the overpasses. Cougars and black bears like the underground passages.
Where: Banff National Park, which covers 6,661 square kilometers of mountains, glaciers, meadows, rivers and hot springs, receives 4.7 million visitors per year. When established in 1885, it was the worlds third National Park. It is one hour west of Calgary."
And as an aside, if you say "-40°" it doesn't matter whether you mean Celsius or Fahrenheit. They're the same temperature.
