DR Jane: I keep forgetting to ask, and just now remembered --
How long is all of that driveway? Is there some reason you don't use a snow-blower or something to alleviate the need for shoveling those huge areas?
I think in these terms because my driveway is a horror in winter. It's a couple of hundred feet long (don't know exactly), and hilly. When we get any real snow covering, my neighbor very kindly plows the whole length of it. I then run the snow-blower up and down once just to clean up where necessary, do the whole turnaround area at the house and garage, and that pretty much limits shoveling to just around the house.
