Left Dana Point at 6:15 with 2 scoops of decent sardines, absolutely gorgeous clear morning. As we got closer to the 209, about 8 miles north of it, the fog bank loomed and I questioned whether we should head into the fog with crappy visibility or stay in the clear and be able to look for tuna signs. We were trolling a ballyhoo and 4 marlin lures, made the call to continue towards the 209. About two miles into the soup, with only a 1/4 mile visibility, saw a boat parked directly ahead of us. As we motored around it noticed they were bendo, so we brought in the marlin jigs, threw a net full of bait out, and shut down a respectful distance away. Literally within 15 seconds of my bait hitting the water I was on! There were only two of us drifting there, by the time the fog lifted I think the armada had about fifteen boats on the spot. If I remember correctly we were around 33.12 117.53. We put 4 on deck fairly quickly, then the bite slowed. We then moved to a different armada about a mile away, actually pretty hard to find in the fog, and set up a good 1/4 mile from the fleet. Wasn't more than 2 minutes of chumming before we were hooked up, had a nice double going. By 12:30 we were done, going 7 for 9 hookups, with 2 fish biting through either 15 or 20 lb. test. The grade was from 15 to 26 pounds, respectable. As I was cutting on the way in, we were trolling the marlin jigs again. Had a quick zip on the Moldcraft black and purple on the flatline about 12 miles from Dana, and came across a school of tuna jumping completely out of the water but 8 miles from Dana Point with no one around at all. As we were out of bait, we just kept going. They're out there, they bit today, from the stuff we heard on the radio sounds like a lot of anglers did well.
