There are currently unmarked white, 2004 explorers on the freeways. CHP< has them, only thing that you can tell by, is the door isignia star. I almost got tagged by one tonight, on the 101, just north of the 405. This CHP was pulling over a van that wanst stopping, he might have thought it was a joke or somthing, but yes... Hes a real cop. BEWARE< watch for those headlights in your rear view mirror.... Just another set of lights to remember for us fellow stangers. MIKE>
