While traveling west on Interstate 70 not too long ago, I glanced in my rearview mirror as I prepared to switch lanes to pick up the eastbound U.S. 40 exit.
Then, a thought came to me as a frightening sight closed in.
There they were, two people maybe in their early 20s, having what appeared to be a blast. He was driving and she was the passenger on a motorcycle whisking them along the asphalt at -- judging by my speed of 65 miles per hour and the rate at which they were gaining on me -- a velocity of somewhere in the neighborhood of 80.
As they weaved dangerously in fairly heavy traffic, I wondered why they didn't display a bit more brains.
By this time I could see neither of them was wearing a helmet. I then thought of their brains again -- this time what they might look like on the pavement.
