well, recently here in northern indiana and in chicago area( i beleive) there have been these wierd wires held flat across the road with a box on the end, there are 2 that are spaced like 2 ft apart, i was always trying to figure out what they are but never could till now, they are a new type of speed trap, they figure out ur speed by tioming how fast u go from one wire to the next, then it uses sattelites and crap and somhow gets ur plate # if ur speeding, hehe, just thought i'd post becaus eit was kinda interesting
