Interstate 55: St. Louis, MO to Springfield, IL

Cahokia Mounds; Mother Jones and Union Miners Cemetery; Robert’s Cemetery and Savanah Nature Preserve; and any of the many fascinating Illinois towns we pass along the way.

Daylight hours are best, but, even if you take the tour at night, it will help the time pass as many of the stories pertain to locations marked by road signs.

Always always always focus on the road, drive safely, and obey all traffic laws. Nothing on this tour requires your immediate or prolonged attention. If something you hear inspires you to explore an attraction further, turn off at the next Interstate exit and take local roads to where the attraction is located. Your best view of every attraction is NOT from the Interstate, so do not pull over or slow down because of the tour.
Keep in mind that it is against the law to stop on the Interstate except in the case of an emergency, and, it is also the law in Illinois that the only time you should be in the left hand lane is when you are passing another vehicle or when you are giving plenty of space to somebody on the right-hand shoulder of the road.
Finally, as everybody’s speed varies, and unforeseen circumstances such as weather or traffic can result in varying speeds, you may experience some brief periods of silence between attractions. However, once you reach the next trigger point, the relevant audio will automatically begin playing so there is no need to look at your device while you are on the tour. If you do somehow go off course, some guy with a pretty cool accent will tell you so over the app. Also, speeding excessively will result in you passing through trigger points early which throws off the synchronicity of the tour and there can be little doubt you will then miss some of the best attractions along the tour.
