The brainchild of 20th-century visionary Buckminster Fuller, the geodesic dome is every geek’s dream home! This airy version, located in Sullivan County, offers a wood floor and screened windows—the rest is up to you! Although the accommodation is BYOB (Bring Your Own Bed, that is), you'll have full use of the outdoor kitchen, shower, and fire pit. Dogs are welcome, but they must be leashed and housed outside the dome; your hosts keep free-roaming critters, including Merino sheep and Angora rabbits. From $350 per night at Airbnb.
