Re: Where to go in OR or WA?
If memory serves, right under the Library. Not kidding. That's one of the problems with Urban rivers, very little in the way of public access. But here's were Google Earth can be a God Send.
Have a King County map in front of you and do a trip up the river. Mark what appears to be 'public,' or at least accessible to the public, and mark with a highlighter.
Edit: Forgot to add. GE has a setting where it gives you the coordinates. Mark these down and punch them into your GPS. You'll drive (close any way) right to the place.
