I don't know about most people but here is why i am selling mine first bluntly then an explanation.

Bluntly: steelhead fishing in the lower Columbia river area sucks..

explanation: I have lived here all my life, grew up on the Washougal river where i used to catch fresh steelhead 365 days a year. now there is real opportunity on that stream probably 50 days a year.
There are rivers down here that have fish at times such as the North Lewis but it is so overrun with sleds scaring all the fish that it makes a day of floating a burden rather than an enjoyment. There is the Cowlitz which is slightly better if you stay above blue creek but that is on the verge of being too far for a day trip. There is the Klikitat for a few weeks each fall but i can have a better day from the bank than floating... The East Lewis? well it's only marginally better than the Washougal but way overcrowded, then there is the Kalama which makes the Lewis look deserted..
i am just sick of the crowds and the extremely poor quality of the fishing and the poor quality of the experience.. I'll just bank fish a few of he smaller streams and catch just as many fish and never have to worry about a shuttle... now of WDFW hadn't royaly screwed up our fisheries i'd keep my boat cause i really enjoyed using it, i just have better days fishing from the bank
