On a good surfers’ beach, usually everyone is in the water. But at 38th Parallel Beach –  near the demilitarized zone between North and South Korea – surfers sometimes see parades with tanks, soldiers and guns. Also in this show: contributor Scott Carrier goes to Hawaii to learn how to surf and test his theory that the music he associates with surfing is the true surf music; and when Matt Brooks and his wife Pam bought an 80-year-old wooden yacht named Dorade, people thought it was crazy they wanted to race it in weeks-long oceanic races. That was until it started winning.
