Snow tunnels are not a good thing and kids are taught so, a little girl died suffocated last fall.
Believe it or not, thick snow cuts down on the cold and is healthy for vegetation. When it piles up too high you can walk out the second story windows. Just make sure you keep a shovel indoors so you can find the front door to the place where the snowblower is stored

:
Remember that this snow fell throughout the whole of winter. We've had all that time to fight it a little bit each snowfall. Around Montréal we've only had 12 feet and two thirds of it thawed when temperatures rose.
Oh, lest we forget... dedicated winter tires are mandatory.
