I'm thinking B- or maybe a B. It was a consistent winter but I'm still 10"-15" below normal for snow. We did get just about wiped out a week or so before Christmas. It never got down to completely bare ground but set back the start of snowmobile season. The cold was consistent, somewhat low grade. We didn't have any truly low minimums but had a lot of low maximums. If we could have held out with winter for another week or so, the grade might be a bit higher.
