As has become our tradition around Columbus Day, we speculate on various might-have-beens - for example, what if Columbus had sailed for a different monarch? - and some of the consequences of Columbus's voyages for humanity writ large. This episode has been revised and re-recorded from those of previous years, and includes some thoughts on "Indigenous Peoples Day," offered by some jurisdictions (and this year as a Presidential proclamation) as a counterpoint.

The image for this episode on the website post is of maize growing in Africa.
