I was on my way to see a friend on I-20 Eastbound to Highway 6. I got a Ka warning of 1-2 strength of C/O Ka outside of Abilene. I went over 2 hills and with the Ka ramping up still. I went around a pretty good size curve and Ka ramping up almost to full with a trooper in sight. 1.7 miles from my first alert was a Tx DPS running his stalker. My friend was riding along and he doesn't believe radar detectors work and i just looked at him and smiled and said it has paid for itself over 30 times easy. I was running 85 in a 70.
