It's been several months ago but I thought I heard an odd sounding " I " car / call sign but I just blew it off thinking that it was one of interstate/traffic guys..... BUT a week, close to 2 weeks after that I got behind a SHP car and it was one of our local pilots that flies out of the Rowan County Airport and I noticed he had an " I " designation on his back glass but I missed the numbers. He was moving when he passed me, LOL.
I just blew it off and thought he either had some sort of spare car or something. This explains what I saw.
