Heavy police present on I-64 near East St. Louis. The cars are unmarked and and use Mustangs, Camaros, and Corvettes. Mostly use X-Band Radar. Numerous speed trap points. Several speed monitoring devices disquised (sorry for spelling errors) as construction signs. Speed limit is 55 in that area, I suggest you obey it. I have see patrol cars in mass quantities several times a month.
