What biking season?

I usually get annoyed when the bike racks on State Street, near the Bike Fed's Madison office, are full and it's hard to cram mine in. But yesterday I had a different reaction.

I went to State Street after work to visit an art exhibits and found this situation at the rack closest to my destination:

Although it took a little extra effort to lock up my bike, my reaction was more of delight than dismay. Yesterday was the first day in Madison with sustained below-freezing temperatures and a pretty vigorous wind. But people are still biking. Who says that Wisconsin has biking weather only half of the year?
