Decided to fish under I90 at Mercer Island from the shore. There's a small parking lot area which leads you down to the shoreline [no boat launch just shore fishing], got there 8:30am. Decided to breakout my trusty yamamoto grub and worked the area. I had several bites but oddly I couldn't hook into whatever was taking my line out. I switched to a smaller hook and a sliding weight to a live nightcrawler and the same business. I have fished on this shoreline twice before and have had similar results. Starting to really wonder what's out there. Any help?
