Although I am guilty of speeding, I gotta agree with FunkyMonkey to a certain extent. A little speeding at 3 A.M. fully sober on the freeway will never really hurt anybody. But going 50 in a residential at 3 P.M. on a warm sunny day is just ridiculous.

Anyway, what radar bands are the cops around you using? Make sure you get a quality detector that can detect all bands. Nowadays, the real high-tech cops can detect radar detectors as well.
