lol...not exactly sure why the bottom half hyperlinked.... ignore that lol
Also, I almost forgot the biggest tips I can give you. First, there has been a lot of flooding this year on the Missouri river. I29 between Kansas City and Omaha, and I29 in and just north of Council Bluffs has been closed a couple times for repair or danger. I think they are open now, and chances are you'll be gtg, but check internet as your trip time approaches ..... they are major corridors, so the priority is to keep them open ..... just thought I would mention it.
But to the point.... DO NOT speed on I29 in or nearing Sioux City. People will be flying past you ..... let them go. Two auto camera speed traps up there on I29 in Sioux City, typically on each side of the city, but they move them around ...... ticket(s) will eventually show up in in your mail box ...... so back it down around Sioux City on the 29.

Lastly .... The annual Sturgis motorcycle rally is Aug 2 - Aug 11 this year. It gets pretty .... ah, let's say interesting and really busy traffic... up there around this time frame....things start picking up steam starting a week prior to official rally through the end.
