I got a two tickets (at different times) about 4 years ago on Hwy 20 in Fl (between Hwy 231- Panama City - and Tallahassee), for doing 62, & 64 in a 55 zone. Trooper said it was a very bad stretch of road that had the highest one car fataility rate in Fl, I still see troopers on the section every time I dive it. Including last week, 8500 worked great.
