Welcome to the group!
There are tons of very active vegan groups in the Boston area.
Boston Vegetarian Association and Boston Vegan Association are two that come to mind. Both pretty big, both pretty active.
Boston also hosts one of the largest vegetarian festivals in the country. I've been there 6 years in a row.
I don't know much about Stamford or what's nearby, but I know there are some active vegan groups in New Haven and Hartford.
There are likely a number of forum members from those various areas as well. www.veganproteins.com
is located just 30 min north of Boston.
All the very best and welcome to our group!
