If I get an inch or two December gets a solid B or B plus grade from me. So many Decembers are just warm and everyone is waiting for mid January. Will get an A from me if it snows again before NY. i don't get upset if I get 2 inches and someone else gets 6 inches. What gets me down is when I get an inch of rain or cold cirrus and 50 miles away someone is getting pounded.
