Rt. 93 in Quincy

He saw a girl driving a black jeep on 93.  He says they were "playing tag" with their looks as they battled the traffic.  He kept trying to slow down as much as possible but they never seemed to be able to catch back up to each other.  He was driving a flatbed truck, she was in a black jeep, and they were on 93 around the Milton/Quincy area.
