If you've ever ridden US129 (aka Deal's Gap, aka The Dragon) you know that it is no place for semis. Tractor/trailors on that road pose a danger to themselves and to others. This past week, a rider was killed by a truck, and a petition is being signed to prohibit commercial vehicles from US129. See the link below:
