You're excused. I wouldn't want to drive a rig on snow/ice either. Hell, I wouldn't want to drive a rig sunny and 70F. With my eyesight I'd hop curbs on every turn and backing in would take hours.
Current winter is a D+/D IMO. Anything somewhat decent before we close out the season may raise the grade into the C's...
62F/Looks like when the front passes through 4-6am is our best chance of thunder/high winds (squall line)...
