Gammon designed educational and outreach programs that immersed visiting students, teachers, and tourists in what it was like to live in mid-nineteenth century Maine. She developed six-month and one-year student internships that awarded college credits for on-site living and study. According to a 1999 article in the Indianapolis Business Journal: "Pennsylvania State University students in Parks and Recreation Management trek to Maine every January to cut ice". Gammon also created three-day-weekend programs for teachers and students, as well as for paying tourists, in which participants experienced historical living and study. Each weekend group was divided into two families, the Waters and the Prays, and each participant took on the identity of a historical personage. Gammon herself enjoyed playing these historical roles; one of her favorite characters was that of Mercy Lovejoy, an early nineteenth-century Maine pauper. Thousands of Maine schoolchildren also engaged in role-playing during annual field trips to the site. By the time of Gammon's retirement in 1991, over 40,000 people were visiting The Norlands each year.
