Big D - check out my thread stikyed at the top of the forum for resources for new hunters.
also, there is a guide to the Willamette river that outlines all the public access areas and allowed uses. ie: hunting. if you have a boat you can get to alot of greenway access that is boat only and provides some decent hunting. i also know guys that float areas and do quite well.
i'll look up the Willy river info and post a link for you..the guide is available for free..or maybe a small fee like 5 bucks.
added a .pdf link in the stickyed thread in this forum. check it out.
