Day 24 will take you from the Mississippi River to the plains of Illinois. Once you leave the Mississippi flood plain, your elevation will hover between 450 and 575 feet above sea level. This is one of the easiest days on the coast-to-coast journey. There are adequate old alignments and frontage roads so you will completely avoid riding on I-70. If you follow this itinerary, you do so at your own risk. Failure to exercise good judgment can result in traffic violation citations, injury and even death. If in doubt, please consult with state and local law enforcement agencies.by fbrusca
