... I have only seen a person
vaping in public once, when visiting Atlantic City, NJ, in the evening on the boardwalk. They were using a cartomizer/battery type system with black battery/carto and blue lights on it.
I'm in Maryland USA btw.
Now, there may have been many times I've seen people using an analog and not noticed (which I guess is the idea) but I don't know that I've ever seen anyone using anything APV-like in public other than that one time.
So do you, and/or have you seen others using one?
Other related questions would be "how often have you seen this where you are?" and "have you seen an increase in such sightings?"
