Re: Fly fishing in downtown Portland
I'm not sure if you can get to it via PT, but there's a nice park I fished years ago where the Clackamas pours into the Willamette that might be worthwhile. I think I fished the north bank at Cross Mem park, not Clackamette park.
Hope you do better than I did. That was just another stop on my steelhead-free tour of OR.
