I don't get out much either, but in the 3 yrs I've been vaping, the "ungodly rare" appearance of a vaper in public (outside of vape shops!) has become slightly less rare -- it's still not really common, but here and there, I do see someone emitting something like smoke, but the thing in their hand is not white, but shiny/sparkly -- I'm a bit nearsighted so that shine/sparkle is the only way I can tell a vaper from a smoker, at any distance.
But in my very first year as a vaper, I ran into a vaper out looking at vehicles at the Chevy dearlership when my husband and I were doing the same, and when ADT came to the door selling security systems, when I mentioned we might be interested due to the fact that quitting smoking meant more disposable income, the guy turned out to also be a recent convert to vaping... and, back in Dec when DirecTV came to interest us in a new communications system, both of them turned out to be vapers too.
The revolution is well underway...
