Today was spent crossing some of the flattest terrain I've ever seen. Illinois, Iowa, Minnesota...
There was one interesting note: At two locations, one in northern Iowa, the other in southern Minnesota, I noticed very large boulders (approximately the size of a VW Beetle) sitting in farmers' fields. They did not seem to be made of local rock, so the only conclusion I can come to is that they are glacial erratics.
Another interesting sight are the occasional wind farms...collections of 2,3,5... 20 windmills in farmers' fields.

The weather for the weekend in and around Yellowstone is calling for rain...and snow!
