I was there from 70-72. Party school. But Bucky Fuller was there and I took his World Game class. Lived for 10.00 a month rent in a small geodesic dome just outside town. It was built next to an old farmhouse, on telephone pole stilts, with a trap door in the floor for an entrance. I used to park my VW bug under the come and climbed on the fender then hood to get inside. Yes I was a sort of hippie. Outhouse on the farm and a pump for water. Water jugs on the back porch for showers.

There are lots of nice places to explore in SI. Some over in SEMO, too: Johnson Shut-ins is great (especially on a hot day!)
