Oh, One More Thing

I forgot to tell you more about the recycling polycart.

When I dragged it across our snowy driveway, I figured that it just seemed heavy because the wheels couldn't turn in that much snow.  When I opened it this morning (a day and a half later), in order to put a piece of cardboard inside, I saw somewhere between a gallon and two of water inside.  I had to turn it over to drain and dry.

Gee, it must have snowed *a lot* to produce that much water.  Just how much does it need to snow to produce that much water inside a container whose lid is closed?!
