I'm planning a west to east crossing of Iowa this summer (mid August). We plan to drive from Salt Lake City to the Moline, IL area for my wife's class reunion. I though she could drop me off right at the Nebraska/Iowa line, and I would head east to the Illinois border to join her. She'll be driving along I-80, so a route not too far off I-80 would be great as a drop-off point.
I looked at U.S. 30, but from the photos I could find, the shoulders look like gravel. Any suggestions? Any books that might be helpful? Thanks, OHB
