Frank LoPreste's Royal Polaris has left for southern waters, on the annual Jerry Brown Line One expedition. This is the famous 18-18 trip, with 18 anglers out for 18 days. Billy Santiago Jr. is the skipper on the adventure. We'll have more to report after the boat reaches the fishing area, 1,000 miles south. Giant yellowfin tuna and wahoo are the sought-after species.
