Hi Shannon,
I do a bit of crossfit too when I can (ie.. when I'm not injured and can find a few extra bucks). I love it. I always say it is the only workout that has ever made me sweat. I'm in Canada and I'm always cold tho - that may be a factor .. lol.
They don't know I'm vegan where I work out but I'm thinking I'll just show up in a vegan t-shirt one day... it might make them feel awkward about all the times they were dissing 'vegetarian' diets in front of me.

Checked out your blog... not a fan of the first picture that comes up - ugh. Fortunately I've never gotten good at kipping so I haven't had any tears. Looks like you're lifting some pretty good weight in 4 months.
If you haven't found it already there is a crossfit group on Facebook: 'crossfit vegans and vegetarians'. There is some good info posted there. A bunch of the members have blog posts that they post there which are interesting. And some of the members are into vegan paleo if you are interested in that sort of thing .. (I'm not).
Welcome.
If it's important to you, you'll find a way. If it isn't, you'll find an excuse.
