In spite of what we’re told in drivers’ training, a lot of us brake for animals. I had a friend in high school who had a bumper sticker on his wheelchair that read, “I brake for hallucinations.” But what is a big heavy train, moving at high speed, supposed to do when it chances upon Greenpeacenicks and friends chained to a railroad track? Actually, they probably tipped the train people off about the “surprise” demonstration, as even they must understand the time-component in the denominators of pertinent mechanics equations. The demonstration was staged in order to protest coal mining in Catawba County, yesterday.
