Last year I was proud to ride through the entire winter. I was beat by the weather only once, when my chain broke in 6 inches of snow. But that's because it only snowed once last year.
This year has been an entirely different story. I've been beat down by the packed snow ruts and berms. I've found that I personally do not care to put myself in great danger for the sake of claiming to be a die-hard commuter. In short, I have limitations on my bravery (read "stupidity" if you are not a cyclist).
But you know what is great? Reading. I love reading while riding the bus.
