I could see the ambulances from my spot in traffic... right where RT-7 merges onto 66-W. I was coming home from D.C. and traffic stopped promptly around 3am. I saw some people walking around the ambulances but that's all I could see. After waiting about 40 minutes in the traffic, people started to turn around on 66 and drive down the shoulder to drive down the Rt-7 onramp. HORDES of people. Basically a 2-lane blockade on 66-W, took about 7-8 hours to clean up all the body parts... just crazy.
My roommate was friends with him and his GF, so tragic.
