I had a blast riding around today. I was going through queen's park for a while testing out my winter fixie in the snow for the first time. I was doing full out 2 wheels skids across the fresh snow and skids where I would actually be able to pedal backwards for reverse traction and all kinds of fun stuff. On the road I had to be a little careful because my disc brake locks up the front wheel into a skid if I'm not very light handed.
It makes riding much more interesting to say the least.
