This week on Dirt Talk, Alex and Aaron talk about traveling to Starkville, MS via the Natchez Trace and the increase in trucks due to e-commerce. They also discuss the challenges of greatly increasing the rail system in the United States. Later, they further investigate the American infrastructure life-cycle before broaching the (sometimes) complicated topic of oil and natural gas and its difficult PR relationship with the typical person. Then, they answer a question about the need for "operator classes" in community colleges, and the broader challenges and opportunities related to that.
