On ka! okay there's a bridge over the bridge about .4 ahead there's a school zone. There's a hill too, i got the alert .5 before the hill then .5 later the bridge ends. After the bridge there's a curve and a slight up hill with traffic jammed. The first beep was a slight 2 hits and stopped and i thought instant on? oh noo....come to find out constant on ka and a whopping 1.4 miles. I don't have time right now but sometime today i'll have a map with the dots on it to show.
