Last year, I rode to work before hearing that we were expecting 6-8 inches of snow + wind. I left during the storm and dragged my bike to the Express bus stop thinking I could hitch a ride home on the bus. 45 mintues later, the bus hadn't appeared and I began to wonder when hypothermia would be a factor, so decided to walk the bike 1.5 miles to the nearest non Express bus stop.
Got about 100 feet through the snow (sidewalk wasn't ploughed...) and realized the walk would take forever, so got off on a side street and found a tire track left by some huge SUV. Got in that thing with my bike tire and rode to the bus stop. Was probably doing a top speed of 3mph. There were several times when the snow in the track thickened and I had to stop riding and walk through some drifts. I thought I was set for a nasty spill, but actually got through without incident.
As I arrived at the stop, the bus was just leaving, but driver stopped to pick me up. There was no one aboard. Got my bike on the front of that thing and got home.
