Thanks for the advice gentlemen.

One question that I am a little unclear about. I have decided to drive to Seattle to ship my truck. I am fine with the trip except for whether or not to stay on I-80 past Chicago into Iowa, and NE, and up to I-90 at some point - I-29??
OR
through Chicago to grab I-90/I-94.
Which way would possibly be less traffic? and less confusing?

Thanks so much.
