We got 6-8" of heavy snow Tues and 40+mph winds Wed, so yesterday was my first outing with the winter bike and studs. 20 miles was enough. It's always hit and miss this time of year as to which roads are good and which aren't after such a storm. A lot of snow initially melted and froze, so shoulders weren't so great in some areas. Slop from the lanes was thrown onto other shoulders, and some were bone-dry. I had to take the lane more than I liked, but traffic was fortunately light. Yes, 20 miles was enough for the first outing.
