First stop, we head to Cleveland Ohio by our chartered "bus". A few light snacks and beverages help us settle in for the ride. **Garrett Morgan -- Three Position Traffic Signal** I can imagine Morgan on a busy street corner in Cleveland, and thinking of a calmer, safer flow of traffic — a world where chaos could be lessened with a simple, brilliant signal. He invented the three position traffic signal, dramatically improving road safety nationwide, and forming the basis of the system we still use today. He also created a safety hood that helped firefighters breathe in smoke-filled areas. Have you ever witnessed a traffic accident at a red light?

Next, we scan our tickets on our phones, or show the paper copy as we board our "train" bound for Washington, D.C. Onboard snacks and sips make the ride even easier as we roll along, enjoying the scenery. **Charles Drew -- Blood Bank Pioneer** In the heart of Washington, D.C., Dr. Drew envisioned a system where blood could travel farther than any ambulance, saving lives before help even arrived. He revolutionized medicine with his research on blood plasma. This led to the developing of large scale blood banks and improved methods for storing plasma. His work became the foundation for modern blood donation systems, transforming emergency medicine and wartime care. Have you ever used the services of a blood bank?

Our "plane" is at the gate, and we are welcomed aboard for our flight from Dallas to Chicago. A quick tray of snacks and a drink keeps us company as we fly. **Otis Boykin - Pacemaker Improvements** Boykin studied the heartbeat of machines imagining a future where tiny, precise resistors could help protect the most fragile rhythm of all — the human heart. He created a more precise electrical resistor used in pacemakers and many electronic devices. His innovations improved reliability and accessibility in medical and consumer technology. Do you have a pacemaker?

And now, we settle into our comfy chauffeured "limo", cruising the highway from Mobile to Atlanta. Chilled drinks and small treats wait for us as we cruise in comfort. **Lonnie Johnson- Super Soaker ** Growing up in Mobile and later tinkering in his Atlanta workshop, Lonnie saw possibility in every burst of pressure and every stray idea. A former Air Force and NASA engineer, one of his ideas would become the world famous Super Soaker, one of the world's best selling toys. He is an inventor holding over 100 U.S. patents, and president and founder of Johnson Research and Development. His engineering work also contributed to spacecraft systems. Are you familiar with the super soaker?
