Jan 23 2003 at 1:30PM. Driving NORTHBOUND Hwy 69, over Lake Eufala and JUST BEFORE the city of Eufala: notice VERTICAL WHITE marks on along the right side of the highway. These marks are for the AIRPLANE ABOVE you to time you! Better slow down! I had cloud cover and saw no plane, but the cop told me it was there and that no radar is involved, though my detector chirped a couple of times oddly. He said that they do random sweeps but usually do only 2 just before lunch and about 10 afterwards. Big ugly stinky SPEEDTRAP! Avoid speeding in this area, the barrier along the highway provides a false feeling of security – if you ever see white vertical lines on the highway, they are for the plane above you, slow down! Your radar detector is useless in this scenario.
