Haha! This is exactly what I was thinking!
I cannot speak for Huntley, but in LITH we are required to remove the snow from the sidewalks. They cannot exactly complain that there is noise if you are following the regulations to remove it in a timely manner. The kids head to the bus early in the morning, and the sidewalks need to be cleared for them.
Snow is something that needs to be dealt with so we can go about our lives. If that means you have to deal with it at 2AM, so be it. That is assuming you are removing it in the middle of a snow storm. Now if it stopped snowing 6 hours ago, and you are JUST getting to it at 2AM, I suspect you can wait until a slightly more reasonable hour.
