Man, I felt bad today. I got a wave from the driver of a yellow C3. I was in tight traffic and couldn't return the wave. He probably thought, there goes another one of those newer vette owners that doesn't know about the wave. So, then I see a red C6 vert coming my way. I give a wave and he looks at me like, "do I know you"?? Now I don't feel so bad. Those folks in the newer vettes don't know how to wave.............
