A quick update:
Rob is riding well and heading toward the Mighty Mississippi. As you can see by the comment from night crew driver Mike Desilet to this morning's update, Rob had a decent sleep break last night and continues to ride at a good, steady pace.
Luis Ramos (day crew navigator) says they are dealing with some more highly traveled roads right now in Missouri, which can be more stressful for the crew than for Rob, since it's harder for the pace van to pull over to the far right to let traffic by than it is for Rob to do so.
I predicted last night that Rob would reach the Mississippi between noon and 4:00 PM. It will be closer to the 4:00 side of that range, depending on any stops he makes in the next couple of hours.
That will be a big lift for Rob as he crosses into another state, and a big lift for me as I will no longer have to type "Mississippi."
