Plenty of NY students attend Grinnell, in fact it New York is listed as the 5th most likely home state of students after Illinois, California, Iowa and Minnesota. My son made new friends among Grinnell students on almost every flight home to the East Coast. However, you won’t get good bagels in Iowa and corn is a topping on pizza.
And you can get away from “your existing world” since 20% of the students are international while experiencing Iowa nice. And get a break with study abroad, the Grinnell in London program is exceptional.
