Low 20s here and I had a couple of very uncomfortable close passes on my way home today.
I live on a rural road with no lights and a 45mph speed limit. It has a really wide paved shoulder, so I usually ride on it. But today the shoulder was covered in snow, and it was very windy. So, I was riding on the road.
Maybe I should have taken the principal position, but it was dark, and cars drive really fast on this road, and I was worried they might not see me and rear end me. So, I was riding near the shoulder, and a few cars passed really close to me.
