John,
Two winters ago here we had a lake effect event that dumped 8" in one hour. I know it's rare, but it happened. I just plowed my driveway, then took the sled only 8 miles away to open the trail head. It took me an hour to get there and back because it was snowing so hard. I got lost on my sled because I couldn't see anything in front of me it was snowing so hard. It was exactly an hour when I got back, and I measured 8 solid inches of new in the driveway. Twas funny though, when I got lost I thought I was driving my sled in a straight line through a very large field. Eventually I found some sled tracks and started following them, only to find out I had made a huge circle and found my own tracks. I must say, nothing beats a good lake effect snow storm.
