Yesterday it was above freezing and raining so the previous snow was mostly slush. I assumed (there's that word) that this morning it would all be gone and mostly was... except for a couple sections of MUP, and at 28F those sections of slush had turned to rutted ice. Slipping wasn't the issue. it was maintaining control while bouncing around, because of course I didn't slow down. Almost lost it once and that was enough to scare the crap outta me and then I did slow down. Yay winter...
