I've been to a few of the local vegan meetups here in Calgary.
My boyfriend came with me to the first two, and my best friend, also a vegan, to the third. The first one had 4 people including my boy and I, the second had 5 including the two of us. The third had 9 or 10 including my friend and I.
Just as I was heading off to my vacation, I joined up to help with a new vegetarian group and their things have 12-15 people averaging, so far, and it's only 6 weeks old. I'm hopeful that the meetups will get better, as we're not forcing them to be strictly vegan, but just veggie, in the hopes of building stronger community.
I'm pretty shy when not around a bunch of friends, but it feels good to meet other veggie folks and start feeling like there's some community, especially if you really don't know of any other veg*ans in your area.
I totally recommend doing the meetups if they happen in your area, or setting them up if they don't. It's fun to meet people!
Plus there's a new veg cafe that opened, run by a vegan, that I never would have heard of were it not for meetups. I finally get to go there and try it! Yay for vegan goodies!
