I'm outside having a smoke and I notice a white tahoe with black tint and some weird antenna's on top of the roof. I tell my friend that tahoe is a cop. As the leo gets out and walks into the store, I wait til my smoke is done and start shopping. My main objective was to find that leo and ask him what radar gun does he use in a non-obvious way. I spot the leo in Isle 13 looking at a gun mag. and I stroll by and ask him how does he like his tahoe, I like it alot...blah, blah, blah...then ask him whats he using for radar, is it single or dual antenna'd? He says it's a Ka gun, I then ask him is it a talon or decator? he then tilts his head and says its a Decator single antenna. the leo then tells me that he doesnt like to run traffic much and doesnt really use it much and doesnt use VASCAR much any more either. I then said thanks and told him to be safe and watch his 6 and have a good nite. I thought to myself, did he think I would think that VASCAR is a radar gun? or did he once fly planes and use vascar? This was in Puyullup, WA.
