On Episode 141, my friend and climbing advocate, Sam Lightner, returns for his sophomore appearance on the Enormocast after joining us way back on Episode 9. Sam just recently published a book, Heavy Green, about a battle in the Vietnam War that involved a climbing twist as the NVA were faced with a climbing crux for a daring attack. Apropos, since Sam’s interest and admiration for Southeast Asia has been a decades long pursuit. We also talk climbing opportunities in Laos, the current scene in Thailand, and bolts. Sam’s been on the front line of bolting and climbing conservation for years, and knows the difference between a bomber bolt and rusty death-bomb.
