While traveling south on highway 6 while still a considerable distance from the town the speed abruptly changed from 70mph to 55mph. immediately after passing the 55mph sign a police officer sitting in the median blacked out while it was raining kicked on his lights and pulled me over. I was ticketed for 74 in a 55. The police officer acted quite unprofessional during the stop and was very rude and hostile towards my wife and I when I asked him if I missed something indicating an upcoming speed change. I asked this question in a completely courteous manner as I was simply curious why the speed change so far from the town when there was no change in the road, landscape or any built up areas remotely near the speed change. I saw an officer in the same position on the opposite side of town clocking at the sign when exiting this little village.
