First I spent some time in the East River college towns of Vermillion and Brookings. A hop, skip, and a jump from the Minnesota border, this here is Prairie Home Companion country. It’s a land of hot dishes (casseroles) and Lutheran churches. Of sprawling horizons and “Oh, ya know.”
There’s lots of tall people. Lots of blond people. Lots of tall, blond people. I like it.
But after a week of researching and visiting old friends, I left behind the Scandinavian heritage and Minnesota-style niceties of eastern South Dakota. I made my way west across the Missouri River and then headed north. Actually, I crossed the line into North Dakota; Sitting Bull College on the Standing Rock Reservation is actually in the No Dak town of Fort Yates.
I’m happy to give the tribe some money, so I spent a night at the tribally owned Prairie Knights hotel and casino. I had a mind to play some poker, but when I went downstairs to investigate, I found the card room was already in the thick of a Texas Hold ‘Em tournament. So I bought a sandwich, returned to my room, and watch Derek Jeter’s last game at Yankee Stadium.
After Standing Rock, the plan was to go straight down the gut of central South Dakota to Rosebud Reservation, which sits near the Nebraska border, and then westward to Pine Ridge Reservation in the state’s southwestern corner.
If you were to plot my herky-jerky route across South Dakota, I suspect it would create an exciting new shape that mathematicians would get wide-eyed about.

And of course it will have some mysterious relationship to Pi.
I can imagine this because I haven’t passed a math class since the 10th grade. Read more »
