We turned around.

Well, we were on our way to Detroit and people kept going in the ditch and a big truck spun out and crossed right in front of us ending up on it's side in the median. The roads looked totally clear but they were icy. There was no way we were going to make it in time for our appointment going at a safe speed so we re-scheduled for next week. I hope it's better by then. We were pretty bummed after that.
