Today's guests, Roman Mars, creator and host of the (very) popular 99% Invisible podcast and 99PI colleague Kurt Kohlstedt, want you to ask that question about the mundane — and therefore invisible — things that surround us. Why are stop signs red? What do those spray painted squiggles on sidewalks mean? What are those round things that keep us in our lanes on the freeways called?* On a virtual book tour, Roman and Kurt talk with Lisa about how the pandemic necessitated quick, smart solutions to new problems — think of those feet-shaped floor stickers at the grocery checkout — and how COVID might reshape our cities.
