Retired Captain David Greer joins me again on the show to talk through the changes he saw in the country, the industry, and the river, itself, over the decades he spent shoving cargo up and down the waterways of the Americas.

He'll open up the new show, "The Merchant Mariner Podcast," in early January. The first series on the MMP will focus on the History of Steamboats in the United States. Between the Levees will continue as well as guests find time to sit down with me. Thanks for sticking around!
