In this Between the Levees exclusive, Retired Captain David Greer joins me to discuss river history, his great grandson, and his evident passion and interest in the physical geographies that provide our way of life between the levees. There are brief interludes throughout as I read one of many poems he's composed in his retirement. Please enjoy "Walter and the Green Man"

Captain Greer joins me for season 2 in mid-January of next year.
