Rip Carlton began fishing crab in Alaska about 46 years ago, starting out as a deckhand, and working his way up to captain. When he’s not helming his boat, the Patricia Lee, he lives with his wife in Bend. The Discovery Channel has asked him a number of times to appear in its show “Deadliest Catch.” After many years, Carlton says, his son convinced him to say yes. One of the episodes he’s featured in airs tonight. He joins us to tell us more about the dangers of deep sea crab fishing and what filming the show was like.
