Saturday I attended (my second) Boston Vegetarian Society Festival. It's a very popular event (i.e. super crowded!) held in a college gymnasium. The event draws people from all over New England, excited to hear speakers, meet cookbook authors, mingle with food/clothing vendors and sample lots of food and drink samples.
One of the vendors I like is the Herbivore Clothing Company. I didn't get a t-shirt this year, but if you've seen me wearing a "I'm vegan and I love you" shirt, this is where I got it last year!
