I was on my way home and i got a Ka detection of 1-2 strength. I started slowing down after the second Ka warning. There was a Tx Dps running C/O 2.4 miles away. I got some video of it but it was dark and the video sucks! I was running 78 in a 65 when i got my first alert. I'm not suprised he was running C/O cause it was getting dark.
