My family and I (2 adults 2 kids 13 and 9) are planning to drive from SFO to Chicago via I 90. We are planning to leave by early June. We would like to be on the road for about 4 - 5 nights (maximum 6). (We are not considering going via 70 or 80).
Some specific questions would be:
1. What are things we can see on the way besides Mount Rushmore, Minneapolis and Salt Lake City.. (we are considering going further north to yellowstone.. but dont know how much of a detour that is going to be).
2. Reasonably how many days is this trip going to last.. Has anyone done it and have any interesting ideas and suggestions enroute.
3. Hotels.. Should we book in advance or just drive as far as we can everyday and find a hotel in the evening.
