Nitpick: When Charles is preparing to leave to find work, Caroline asks him how far he thinks he'll have to go. He replies, "I don't know. Maybe a hundred miles or more. Maybe even as far as Sleepy Eye or Mankato." Sleepy Eye and Mankato are only 37 and 74 miles from Walnut Grove, respectively, so this line is geographically confusing. Charles should have said something to Caroline like, "I may have to go to Sleepy Eye or Mankato...maybe even farther." The way the line was written makes no sense.
