I have NO experience with traffic. I think Sioux falls (220,000) is bad. Around the mall when the cars are backed up a whole block (in 1 lane) is about the worst I've seen...
I mapped the trip and it would take around 9 hours along with about 3 hours of getting lost and dealing with traffic. I might be able to make the trip with someone else though... I know there's a few people who live in minnesota/Iowa.
These are the SD interstates I'm used to. This is coming into sioux falls from the north.
