I've seen 4 yellow, & 2 blue MP3's, 1 orange & 1 black MSP around the area's I have been. I saw one yellow in Manassas, 1 yellow in alexandria, and 2 other yellow towards the stafford area. One blue in the stafford area and one on the Fairfax County Parkway(FCP). The MSP's, I saw the orange one in stafford and the black on the FCP. All of which are not on this forum!! Why, I don't know... I've never been able to tag anyone, or talk to them. All of them would look as I passed but never got a wave back from any, except the blue MP3 I've seen on the FPC, always wave to him but have yet to talk to him.
