I've been studying the angle of repose.
That's the angle at which it becomes too steep for the snow to stay piled. We have an issue of lack of space. Between the street and the sidewalk and between the edge of the driveway and the house next door, no more snow can be piled. The angle of repose is now to steep and we have to find somewhere else to put the snow.
Meanwhile, BB just called and I have to find yet another place to put my car. :-(
He's on his way home and needs to get into the driveway. My car is blocking it. :-(
