There are about 10 vapers now in the office complex I work in. It started with one guy, and after a bunch of smokers (including myself) saw the success, it has snowballed into a large group of us. We all meet in the building lobby to vape together now, rather than going outside in this 110+ weather. I think starting vaping in the summer in Phoenix has made me enjoy vaping so much better. The other workers in our building are still using there starter kits, so when I come with new tanks, MODs and juice every day they tend to make fun of me, but it's all in good fun.
So besides my office, I have seen 3 in the wild over the last month. The first was at a golf course in Tucson. I was sitting down waiting for a charity tournament to start, and a guy came up to me and pulled out his eGo and said "I couldn't help but notice your eCig"
The second was when I was on my way to get some "vape mail" I saw a lady get in her car and started toking on her eGo.
The third was at the bar the other night, I was sitting at a table with my family and a guy pulled up to the bar and pulled out his eGo and proTank...I made a point to go talk to him and talk about vaping.
The best part about being a vaper is that when you do run into others that vape, everyone wants to talk about it and are very friendly. It's like a club/cult/fraternity
