The length of time it would take to get to "St. Olaf, MN" is very dramatically portrayed in this episode. While on the plane, Rose says that there isn't any reason why they shouldn't be in St. Olaf in a couple of days (48 hours). In reality, if one were to fly from Miami to Minnesota, you would most likely go to the Minneapolis/St. Paul airport. From that point the farthest point to anywhere in Minnesota would only be about 4 hours by car. So, the fact that Rose says it will take 2 days makes no geographical sense at all.
