Due to the lack of bike path sized snow ploughs in DC I have recently been braving regular roads on my commute and its got me to thinking where my optimal road position should be? I used to cycle as close to the footpath as I could but am coming around to the opinion that it only invites cars to try and 'sqeeze' past you.

Now I bike about 1/3 - 1/2 of the way into the lane so cars have to pass me as they would another vehicle. I think I'm safer that way. What do the rest of you do?
