I'm thinking a D grade for the winter. Blowtorch Dec and Feb...slightly below Jan. Approx 11-12 inches of snow which half didn't stick to paved surfaces. Times township snow plows used, once/myself shoveling, once. Brine/salt roads 10+ times in which 2/3 weren't needed which only made my car white and rust the underside/brake lines. No winter storm warnings, no holiday snow (Christmas to New Year)...I'm sure this winter sucked in more ways which I can't think of right now.
