I have driven from Chattanooga to S Fla and back MANY, MANY times over the past 25 years, and got pulled over ONCE in Volusia county, Fl. And that was during the great "Profiling" days! Drive a car that is legit, check all the lights whenever you stop, look mainstream, and drive conservatively. Unless someone turned you in, there is no reason you should get pulled. If you DO get pulled, then you'd have a very good chance at challenging the legality of the stop. Oh, one other thing. Lay a retainer on an attorney before you go, just in case.
