I visited the Robert Frost Stone House and Museum in Shaftsbury, Vermont (121 VT-7A) just north of North Bennington. The grounds are beautiful and it's fun to walk around and imagine the revered poet living there and tending to his orchards. He lived there from 1920 to 1928 and penned his famous Stopping by the Woods on a Snowy Evening there on a hot June day in 1922.
However, I'll be honest and say, unless you're a real Robert Frost or history buff, you might want to save the cost of admission to the house. There isn't all that much inside other than placards to be read. I was annoyed that photos aren't permitted inside the house, which is a bit weird. Instead, you might want to just take a stroll around the outside and, if you're a walker, take the short hike along The Robert Frost Trail (click here for trail guide).
My visit did inspire me to purchase the American Library edition of Robert Frost: Collected Prose, Poems and Plays and Robert Frost: A Life. Frost is highly regarded for his depictions of rural life and command of colloquial speech.
