Just wondering how popular vaping was in your area. I am in southern California and it is definitely taking off around here.
Portland, OR: I only know of a few shops and outside of work, I haven't seen any vapers. Where I work however (a rather large corporate office) I'd guess that 15% to 25% of folks in the smoking areas are now vaping.
In this town you can't throw a brick without hitting a vaper. That's actually a good thing because if they have a good mod, you can take it while they are out cold.
