I'm taking a trip to Portland, Oregon in a few weeks. Does anyone know any easy access locations for any types of fish? I am from middle of nowhere Vermont and know next to nothing about Oregon fishing

Check out IFISH.net.  It's a local website about fishing.  Willamette river runs right down the center of town and can be good.  Summer is tougher but catching can be done.  If you can get out early try up by Oregon City on the east side.  There's a big park where the Clackamas River comes in.  Try a pop r...or swim a small grub.  Was quit a few smallies in the area and lots of bank.
