A long snow pile that forms in the middle of a wide town road after it's plowed. The snow pile is often not traversable without the most hickest of pickup trucks, so it essentially functions as if a median was installed on the road.
I was goin out fer a rip on the old snow cat when I got to main street and saw the plows came through already and formed that Minnesota Median that always shows up around there.
That's when I decided to take my snow cat and jump the Minnesota Median and oh you betcha that was the best thing I've done on rip in a while.
