Teacher, research and author KELSEY FREEMAN joins Marc and Dave for a conversation about immigration and US policy. Kelsey spent time in various locations in Mexico, including Celaya City, where she discovered that migration north is complicated and very very dangerous. Her book is called "No Option But North: The Migrant World and the Perilous Path Across the Border." Plus music from Santana ("Migra"), Calibre 50 ("Immigrante") and Luba Dvorak ("American Sin")
