Yesterday and Friday I saw PSP using a novel tactic on two different highways. Friday I was heading north on I-81 about 5 miles south of the Susquehanna River (just after the 581 east split) and saw a marked CV "hiding" in some shrubs off the right berm. I instinctively slowed to the PSL even though my V1 was silent. As I passed I saw him holding a Kustom HR12/Falcon out the driver window like he was using it but I never got a warning.
Sunday I was heading north on US15 about 5 miles north of the MD line and saw another marked CV in the median near a Gettysburg exit working the southbound lane (he was obscured from them by an underpass "mound") and once again he was aiming a Decatur Genesis out his window at southbound traffic but I never got a warning from the V1.
During either trip my V1 did false at the usual spots so I believe it's working OK. I guess "Operation Impotent Intimidation" was the name of their Labor Day activities! :P
