Trip north began in LaPlace, a little town just north of NO,
and ended where Hwy 61 ends in Wyoming, MN.
Here's a view of 61's path from space. (Full disclosure: I didn't take this picture.)
What starts out as the "Blues Highway" in the South
becomes the "Great
River Road" somewhere in Missouri (where it's also dubbed "Little Dixie Highway," a bow to Missouri's
border state past),
into Iowa, along the border first with Illinois,
then on north in Wisconsin and finally Minnesota.
This last stretch of the river (which goes past Wyoming to its source at Lake Itasca--I didn't make it that far, but next time for sure!) is known as the "Upper Mississippi."

here.
