It was pretty slick but I kept control of the car pretty easily, and went about 20 most of the way. I was concerned about the two hills between Corvallis and Philomath, and sure enough on the second hill everybody stopped. I was SO glad I ended up on top of the hill instead of on the incline. The guy behind me wasn't so lucky and he had a heck of a time trying to get his car to go once we were started again. Apparently some of the people had been stopped for ten minutes, but I only had to deal with it for about three.
So everything's OK. You can breathe again.
