Thanks, I am mostly laughing at myself.

I was able to get up the hill in the morning, the road was pretty clear, but going down at night was terrifying. It got warm in the afternoon, enough to melt some snow, then the melt got frozen later on when I drove down, so it was like ice skating downhill.

So, I joined the chorus of people advising the OP to get appropriate tires, especially if he's going to Bolton!
