As far as sidewalk cleaning here. We are recommended NOT to clean them at all. If we clean them and there is a fall, we are liable because we did not do a good job. If we don't clean them, it is walk at your own risk.
As far as the snow being packed on the streets until April if you don't plow, so what, Don't drive, don't bike. Walk. Snowmobile. Sled dogs, I can see a whole new industry breeding, boarding, selling sled dogs,and building sleds. Sounds like more jobs to me.
