I had a two amazing Ka CO encounters this weekend. Driving across alligator alley in Florida I had a 4 mile Ka FHP detection. On the way back a 2.5 mile reception. On the 2nd encounter, the LEO was just over small bridge, so he was not visible until to crest the rise in the road (they really aren't tall bridges, just humps in the road for water flow. I kept waiting for the LEO to be beyond the next hump, as the V1 said it was a forward detection, but the beeping went on for miles and minutes.
For those that don't know Alligator alley is a long, flat stretch of I-75 that connects Naples and Ft. Lauderdale.
