(me included) besides being below freezing (23 degrees according to the sign on the way home), the fog was awful..wasn't too bad around my house but by the time I hit the freeway you could barely see in front of you..getting off the freeway you couldn't see off the side of the road and since you were traveling slower and couldn't see landmarks it was hard to judge when your turn was coming until you were right on it. (country roads with no lights)..Anyway..I made it (I had to I was the instructor for this class) as did 6 other people..so we had fun for an hour ended class a little early (was suppose to be 1 1/2 hours) and every one was ready to brave the roads again..yeesh just as bad coming home.
