While in college, I lived and worked off campus one summer. The work meant I had to ride up a pretty good hill on a fairly busy highway on the way home, often at 2AM. One night I am going up the hill and I hear tires behind me, slowing. I kind of cringe as I figured I was going to get a bottle thrown at me or some sort of harassment. Pickup pulls up beside me and paces me for about a minute. Now I am really nervous. Window comes down and I hear, "Twenty up this hill. Pretty damn good." And off he goes.
