[Maroon 5.0 LX]

Although not much use in residential areas, a CB radio is your best "radar detector" when on the interstates. Just put it on channel 19 (in most areas) and listen to the truckers.

Truckers know where every cop is, in the bushes, behind signs, in plain cars, overpasses, etc. Lots of troopers aren't shooting radar, but just looking for speeders. Those truckers can spot the law everywhere.

I go to Florida twice a year, and the CB is the best investment I've made. I have a radar detector too. Also, if there is a big traffic tie-up, or accident, the truckers are telling their buddies about it, and you can change your routing to bypass the problem.
