If you are the type to try cycling in winter, you will arrive at a nice mix of clothing, footwear, tires and other stuff without me or anybody else telling you what to do, if you are at all determined. Same for the bike you choose to ride. That said, here's the one thing I would like to share or recommend about cold weather riding: get goggles. You won't know how you did without them if you do.
Clear (unless you only plan to ride in bright conditions) goggles have been by far the best addition to my winter riding getup. They provide a warm and protected place for your eyes, and when you're not crying or feeling your eyes dry out in cold wind, you ride better and enjoy it more.
I use motocross goggles, but I strongly suspect that most winter goggles would be just as good. That is all. It feels very strange refrain from being odd or stupid or overly personal in one of my blog posts, particularly on a Monday... but for a change I have nothing more to say, and since everybody knows what a pair of ski goggles look like, a picture would be superfluous.

PS - Doing a post this direct and nonsense-free is killing me. Stay tuned for something extra stupid sometime soon.
