Steve, see this thread http://washingtonflyfishing.com/board/showthread.php?t=36870. The salt won't hurt your gear, just wash it down. Do a search on the site for sea run cutts or resident coho and you will find a ton of information on the type of beaches to look for. From my experience, the residents hang out around points or upwelling areas where the there is alot of circulation. I would hit up Lincoln park for resident chinook - there is another post somewhere about it. It is a good spot with alot of beach.
