The Sammamish River and north end of Lake Washington are a lovely place to paddle! If you can arrange a shuttle, I recommend leaving a car at the Kenmore Boat Ramp, and putting in upstream at Wilmot Gateway Park.
This should be an easy find. It's a soda tube tied to a small metal sign post.
Enjoy the water!
Congratulations to 2 leep for a wet, well-earned FTF!
