On the road from Dallas to Austin is Italy, Texas: home of the Monolithic Dome Institute. I can’t offer up much explanation, here — I played with Aidan in a big empty field while Mary walked around inside the visitor’s center. When she came out I asked what she’d learned, and she said “Not much!”
My best guess about this stuff is that it’s sort of a resort — only instead of the attraction being scenery, or a canyon, or a waterfall, people come to see the wind.
