Well, security at San Francisco didn't bat an eye. I had my whole kit in my backpack, which includes 2 complete setups, and 4 extra clearomizers with a packet of coils and a bottle of juice. While waiting for the plane, I just moved to a quieter location away from the crowd and didn't make a big deal out of it and vaped away.
It was interesting. We changed planes in Atlanta. I had never been to Atlanta airport. They have "smoking rooms". It was a little weird. My wife and I decided to just use the smoking room to vape in - when in Rome, ya know. It was actually pretty disgusting. This is the first time I was around smokers like this since I quit. There were maybe a dozen guys in there. The first thing was the smell. Wow, even with the ventilation fans going it was pretty bad. Then I just noticed that most of these people looked depressed and kind of sickly and it struck me oddly. 2 months ago, I don't think I would have thought anything of it. These rooms are all glass. You feel like you're in a cage. At one point i could see this older couple approaching the glass doors, they stop at the door and the women fiddles in her purse, comes up with a cig and then comes in to the room with us. The husband stays outside the glass. She's got some kind of 100's and she starts puffing away. On the other side of the glass the husband is patiently waiting for her to finish. Once in a while he looks in toward her and she holds up the ciggy showing him where she is on it. This goes on for a few minutes and I feel for him. I'm so glad my wife and I are doing this together.
