Not everything about the past is tinged with a golden glow. Unless you like golf ball-sized protuberances jutting out from where your knees and feet rub on your longboard while paddling. In the ’60s, “Surfer’s Knots” (or surfer’s knobs) were common (but weird) enough, that Time did a report on the things in 1965, reporting stories of San Diego doctors who’d cut ’em away for $15 a pop. The good old days, huh? Hey, at least they kept you out of the draft. Remember the cane-whipping scene in Big Wednesday when they’re all trying to fool army draft docs? Surfer knots.
