Skid skid skid down the highway

So today was another routine school day. Long hours in the classroom and the library. But after school me and my roommate decided to go to the wholesalers to buy stuff for a student run store in the dorms. Since neither of us own a car, we borrowed a friend's and headed out.
When we left our building it was raining. As we walked up the hill to the parking lots the rain turned to snow and it was accumulating on the ground. We didnt take much notice since neither of us had checked the weather forcast and went on our way.
We took a wrong turn on the way out of campus; instead of taking 9W North we were on 9W South which takes us to the mountain road. The mountain road is known to be highly dangerous in adverse weather. There was snow and ice on the ground and we were driving very carefully.
After a while we realized that we were going the wrong way and turned around. By now more snow had accumulated on the surface. As soon as we reached a turn in the road the car started skidding. We had no control over the car. We were on a dangerous part of the highway moving fast with other vehicles around us. On one side of us was the barrier that separated the lanes, on the other side was either the mountain or a sizeable drop. The car was going the left then to the right and to the left. We skidded out of control for at least 150 feet maybe 200 feet. Finally when we came to a stop the car had completely turned around and was facing the wrong way in the middle of the lane. There were at least 20 other cars stopped behind us. Miraculously and with some expert manuevering from my roommate we didnt hit anything or fall off the road.
The drive to Central Valley that normally takes 25 minutes took us more than an hour. That was some shopping trip!
