Are you new to the world of radar detectors? Well, sit down and listen to your old Uncle LeftLaneInPA. He has a story for you. Yesterday, I was driving through the Lehigh Valley area in Pennsylvania on PA-22 going Eastbound. Before that I was on the Northeast Extension of the PA Turnpike (I-476). Both roads have several areas littered with those "YOUR SPEED IS" traffic signs that use K-band radar, and they're usually arranged in clusters on both sides of the highway. So you'll get multiple hits as you detect both several signs in front of you and those on the opposite side of the road that are now behind you, but facing you. So, I've been getting rather jaded to multiple K-signal alerts at once on this trip. And I'm familiar with PA-22, but not intimately so. I go down that highway maybe once or twice a month. I'm heading eastbound on PA-22 and I know I'm heading towards a "cluster" of "YOUR SPEED IS" signs on both sides of the road. My radar detector setup is a Valentine One paired to a Android smartphone running the excellent JBV1 application. >*beep beep* "K-Band ahead". Ho-hum. >*beep beep* "K-Band behind. Two bogies." Another one of those annoying signs, on the westbound side. >*beep beep* "K-Band ahead. Three bogies." Yeah, yeah, I know. There's another sign up the road. >*beep beep* "K-Band behind. Four bogies." (looks to left) Yup. Another sign. >*beep beep* "K-Band ahead. Five bogies." (yawn) I wasn't yawning shortly after that, just as I spotted the PA State Police trooper who was driving an Explorer in one of the new harder-to-see charcoal-gray coloring schemes. He had backed all the way into a cluster of trees on the side of the road and I didn't spot him until we were literally at a 90-degree angle. Luckily for me, I was going flow-of-traffic speeds (65 MPH in a 45 MPH zone), but if I was going any faster I would have been toast. He was obviously using the "cover" from the K-Band "YOUR SPEED IS" signs to mask his signal. The moral of the story is: don't discount any signals unless you are absolutely sure you know what the source is, and don't let hubris make you unaware. Stay alert! Trust no one! Keep your radar detector handy!
