This is an underrated, gritty gem for nomads. Baltimore boasts the American Visionary Art Museum, with outsider art exhibits by the Flaming Lips’ Wayne Coyne, and Mr. Imagination himself, among many others. Sure, Baltimore is blue-collar and can get rough, but that’s how former denizens like Edgar Allan Poe and John Waters liked it. Bolton Hill has fantastic 19th-century architecture, while Fells Point has diversity and great nightlife at places like Bertha’s, Ledbetters, and The Horse You Came In On. Baltimore ranks tenth in terms of walkability.
