I simply do not enjoy the rain/snow transition that we get here in Michigan. Its tough to plan for. If its just rain, fine. If its just snow and ice, I've got equipment for that. When a rainy morning turns into a slushy evening commute, that drives me nuts.
I had a ride home last year where the meteorologists called for less than one inch of a rain/snow mix and it turned out to be closer to six inches of snowy accumulation. I didn't prepare too well for that.
