SW Washington Steelhead Rivers

I am going to head down to the Portland Brewfest and was wondering if fishing one of the rivers on I-5 is worth it or not. Anyone have an idea?
Try the Northwest Bottlewerks Trippel that Fishtale Brewery made for them. It was cured in an oak wine barrel for two years and it has a 10 percent alcohol rating.

Forget fishing, this is a weekend to celebrate!
