We visited the B+J factory in Waterbury and it was a let-down. Not even a free cone. Meh. My suggestion if you're in the area is to go to the Prohibition Pig in Waterbury. If you're into beer at all, they have the best you can get. And their grass-fed burgers are outstanding.
We also visited Shelburne Farms 5 mi. south of Burlington which is beautiful and historic and I think right up your alley. If you were on a cruise on Lake Champlain, this would be a primo excursion.
Enjoyed the 6 perfect days of weather in the Capital District! Sweating through the FL heat until we leave for Italy in 10 days.
