I didn't get to try it in the surf. When we were checking in, I mentioned surf fishing and the ranger said I could go right off the beach at the park. I was incredulous, but he said he had just had to research and get confirmation from ODFW the week before. So I got up and headed for the beach just at high tide, figuring to follow the tide on its way out, per the video.
Great big "fishing prohibited" sign at the beach. Crap.
By this time, Mrs. Pin wanted to head to town for lunch. Scouted out the south jetty, it was now about 2pm and the tide was on its way out. So I took the rig from the video and just plunked it off the rocks leading to the parking lot. A fellow was packing up and said he didn't get anything but that someone near him got 3 rockfish. I felt a number of bumps and had one fish on the line briefly. I think a #2 hook was too big for whatever was there, which may have just been a crap pulling on my rubber sand worm. A single 3/4 egg sinker held fine.
But yeah I would much rather use this setup than get all twisted up with two hooks and a dropper.
Gonna regroup for two weeks out and try again off that jetty, maybe the beach itself. Looks like there are depressions visible at low tide that pretty well match up with where the trails come from the campground out to the beach.
