Tom Price
In an empty middle school classroom in rural Lancaster County, a mild-mannered math teacher engages in subterfuge.
He speaks animatedly into a video camera, his voice rising and falling as he explains the metric system's many advantages.
"Hi. My name is Tom Price. I'm a math teacher, and I want to change this country to the metric system," he says. "Why? Because two systems do not work."
Later, he'll upload the video to YouTube. He hopes it will light the spark necessary in federal lawmakers to convert the United States to the metric system.
