When I went vegan, I went to a tech school of about 1200 students, and not only did I think I was the only vegan, but I assumed I had to be the only vegetarian as well!
Well, through word of mouth, I found out that one of the math teachers (a genius man really) was not only vegan, but raw foodist (would explain the bowl of fruit in his office)! Not only that but his wife worked for admin and was raw foodist as well. I also found out that one of the security guards on campus was vegan.
Turns out one of the people I had known my whole life was actually vegan too. She lived in my home town of 330 people! I never knew that either.
Vegans and vegetarians are around, but luckily we don't have to wear green V's on us.
I worked at a whole foods in Boston and 6 of the 45 people in my department were vegan, and there were 5 more in the store!
There are 1-2 million in the USA, that's one out of every 280-140 people.
