I will be heading to Portland, OR for the first time to visit my son and want to sneak in some flyfishing. Can you please provide me with contact info of a knowledgeable & trustworthy guide in that area. I am not an expert by an means. I'm not even sure what type of fish I want to go after. We will be in Portland from Aug. 31 to Sept 7, 2010. Open for suggestion. Thanks in advance
