Chipmaney,
I will be in the Seattle area this weekend visiting some friends and picking up a new creeker so I will not be able to boat but I have some friends that will be on the Tumwater tomorrow. If you have not heard from anyone you can give me a call, 425-466-8370 (I know it is a westside # but I live in Wenatchee) and I can hook you up with them. There is also the Tri-Cities crew that will be up in the canyon. Feel free to use the # in the future if you are coming over for Tum, Icicle, or any others.
Have fun,
Chris Ohta
PS - Dress pretty warm. It has been getting pretty cold at night and 50-60 during the day.
