Gees, I can't even fathom what over 4' of snow would look like. I spent part of my childhood in Erie, so I sorta kinda know what 3-ish feet looks like, but that was like 30 years ago when I was a small child. We used to have to hire a backhoe to dig us out since our driveway was so long, and I remember the snowpiles going almost up to the wires on the telephone poles near the road.
That said, I'll be very happy with anything over a foot when all is said and done.
