Went down to W.Spfld today, about 35 miles from home. The St. Patrick's day parade was happening in Holyoke, about 1/2 way, and they closed a couple exits on I-91 going into Holyoke to keep the parade route clear.
Needless to say, there were State Cops ALL OVER the place. I passed one of the closed exits, but when I got to the other side where the ramp onto the highway was a New Charger R/T came up like a bat, got onto the highway, and then came up right on my @ss, FAST!!! he kept back enough so I could see the front of the car, and then I noticed the plate was weird...it was a State plate.
He swung out, and in my car, with the radio on as loud as usual, I could HEAR the engine inside my car, and could even feel it. In seconds, he passed by me like a shot, and probably hit ~100 in a couple seconds more. As he went by me I saw the plate said STATE on the side and OFFICIAL at the bottom, and there were 3-4 high frequency (800MHz or greater) antennas on the trunk. He was getting off at the next exit, so he had to really move to beat the traffic to the exit.
Don't know if it was a cop, but it was dark blue with dark tinted windows (much darker than state law allows...)
