If you had been in Denver on Friday you would have seen one....me. But then again, being relatively stealthy you may have not seen me. While waiting at the gate I try to find a seat near a window. I look at the reflection of the people around me (behind me) in the window and
vape accordingly.... I did notice a woman do a double take this evening in Phoenix. I forgot I was being stealthy for a moment and started to take my usual drag. I just exhaled into my shirt without turning around.
