So road work's about to start on this long stretch of highway that's one lane. One of those stand alone road message board was placed slightly behind the top of a hill. However, I picked up a K alert about .8-1 mile away and was puzzled, seeing that I haven't ran into a cop for a month.
I passed by it the next day from work, and sure enough, K alert from the sign. Now, I've seen a lot of these stand alone boards, but I've never encountered one that gives off a K alert.
apologize for camera phone picture; I forget that its zoom isn't very powerful.
