For some reason the Bliss Brothers Dairy in Attleboro just popped into my head so I Googled it.
Not only is it still there, it appears to have not changed since I was last there over 30 years ago -- that's a very good thing.
My eating itinerary for my next visit to RI just got another stop.
This is a place for the whole family, too. The little ones will love looking at the ice cream making machinery through the big plate glass window in the dining room.
