Look at the WDFW link... www.wa.gov/wdfw/do/newreal/jul2700a.htm
Understand the Muckleshoots did well on their test fishery - can't remember exactly where I read that. Looks like there's 2 time slots...noon Aug. 4th through noon Aug. 7th, and noon Aug. 11th through noon Aug. 14th. I may try it with a friend on Friday the 4th. I'll post back my results if I go.
Good luck - Mark.
