One last, fleeting look at Minneapolis as we head off into the sunset. Bilbao on the Mississippi. It's actually the Weiseman Museum of Modern Art at the University of Minnesota campus, designed by Frank Gehry. Pretty fantastic, huh?

We're now in Sioux Falls, South Dakota. No, I lie. We're somewhere north of Sioux Falls, in the middle of what looks like a corn-field. All accommodation in Sioux Falls proper has been booked out for the past three months, because -- wait for it -- there's a Softball Tournament on, with 60 teams from all over the midwest. So once again, we were miles from dinner last night. Ah, the viscissitudes of travel!

Turns out, there are all sorts of things to do in Sioux Falls on a sunny Saturday morning, including a corn maze. That really does look interesting, but with my lousy sense of direction it would most likely be a big mistake. There's also a winery made out of bales of straw. Corn straw, probably. There's a lot of corn in this part of the world.

True confessions, I wasn't sorry to leave Minneapolis. The art is wonderful, but the roads are a snarling, tangled nightmare, a veritable lover's knot of freeways, which have multiple, often confusing designations (35W for example, goes east) and merge continuously and abruptly into one another. And nobody gives way to anybody, ever. You just wait for a break in the traffic and hope you survive. I thought Barbara was going to have a total nervous breakdown.

Gotta go. Bao says he needs to visit the corn-field and do what dogs do.
