Amazing how terribly some people have missed the point.
The original question asked if it is acceptable. The obvious answer is yes.
The question was not about whether you can or can not physically shovel the driveway.
I could go cut the grass with scissors, but instead humans have evolved and invented tools. The fact that some of you actually view this topic as though clearing snow should be some sort of work out are just idiots. If so then you should also not own a car, lawnmower, or tools. Get a workout and stop cheating with that technology
My awesome snowblower saves time, saves an enormous amount of effort, allows me to sleep more, and does a much better job than shoveling.
Time is money. I don't even really need to pay attention to the weather. If I get snowed in I take 20 minutes to go clear the driveway. Seems a hell of a lot smarter than shoveling for 2 hours and being late to work or wherever else I need to go. Late to work = less money.
But, much like any other topic ever discussed on these boards, there are idiots and azzhole neighbors who do stupid and annoying things. If some idiot want to go snow blow his driveway at 4am after a half inch of snow, he is just an idiot and a bad neighbor. Don't blame the snowblower. Chances are this same idiot neighbor hammers things in the garage at 4am, mows the lawn on saturday morning at 5am, has dogs who bark all day and night, and parks 7 cars in his front lawn, none of which have engines. Don't blame the tools, dogs, or the cars.
