Execellent question! I've often wondered the same thing. Either nobody fishes Colvos below Southworth, or it's a zipperlip. I do know that last year, Pt. Robinson did not live up to previous years averages, but I did see some nice action at Three Tree Point. Redondo was fair to good. I would bet that a good 50% or more of the fish that run down the east side of Vashon, turn the corner at Pt. Robinson(just my opinion).
