When you spend as much time on the road as I do, you see a lot of strange things. And, in the winter time, you see a lot of tracks in the snow from hapless motorist who lose it and wind up in the ditch.
So, one wintery evening, I noticed a tire track headed down into the median. Since there was only one tire track gradually going down into the median, I assumed that the other was soon to follow. But no, there was only one tire track.
This was most unusual; a single tire track rolling along in the median. Then, after about a 1/4 of a mile, a single tire laid in the snow and the track ended.
How did a single tire manage to roll down into the median? Very strange. Then, on down the road, I saw it; a pick-up truck missing a rear wheel.
It must have been a strange feeling to see your rear wheel passing you in the median. Oh well.
