Manchester area. There are still quite a number of old Quebecois here, and they are getting older, but you can still find a few eateries that offer poutine and other French-Canadian specialties..
Most people around here root for the Boston Bruins (including me), but there are still a few holdouts (largely on the West Side) who still root for Les Habitants de Quebec. As for me, I speak French, so I can insult hockey fans in two languages. ;-)
I was on the Seacoast. Certainly some folks of French-Canadian descent, but no poutine on any menus that I recall.
