Day 4 Rapid City to Rochester

Our first destination was Wall Drug.  Obviously, because how can one ignore all those signs?

I-90 going east. Very green, lots of cows and corn. Not entirely unexpected.
Corn Palace, Mitchell, South Dakota
Difficult to resist doing this at the Corn Palace

Corn, naturally

Today was spent driving on I-90 east and nothing else. Crossed the Missouri, one of the great rivers of America. Had a picnic lunch in a public park in Mitchell, to get away from drive throughs. Started listening to our second audiobook, Agent of Change.  The landscape changed slowly from grassland and prairie to the more controlled and segmented farmland of corn and soybeans.  No bison were spotted, which was a disappointment, mainly to Tim.
