Coming off C-470 on to I-70 Westbound I caught up to a F355 Spider. I heard the exhaust from the off ramp and thought, what the heck is that? As I hustled through traffic to catch up I was excited to see this beautiful Black Ferrari! We are in the middle lane and he drops it a gear and takes off. I was in 6th and dropped to 4th and closed on him at about 110. I had to back off a touch so I got in the right lane and passed him. As I got on the side of him he went down another gear! That Ferrari sounded like an Indy Car, it was screaming! We backed off at about 130 as we were approaching traffic. When we backed off he was at my back bumper. We plotted for position once again in the left lane and the one last car that was in front of him moved over and here we go again! I had no room to pass but closed on him again and had to back off the gas a touch, My car clearly had more! It was probably the most exciting street race that I can remember having. We played cat and mouse all the way to the Evergreen exit! My hands were shaking when I got off the highway...Just wanted to share my Ferrari kill story.
