The Avery family operated three very different types of Vermont Inns. They owned a country inn near Dartmouth College in Norwich, a downtown hotel near the state capital in Montpelier and Bonnie Oaks Lodge and Bungalows in Fairlee, Vermont (a television Newhartish setting with a population then of about 600).
The lodge was located on Lake Morey.
The season was from mid June to mid October.
It's unclear when the cocktail lounge was added but it was open through at least the early 70s.
