I know of 2 swap meets in Seattle, usually in the Spring and the Fall, ie; April & Sept or Oct. It's held at Gasworks Park on Lake Union. More info and exact dates can only be found in the free copies of "48 degrees North" monthly circular at marine stores in Puget Sound area. You should be there early in the morning, Saturdays only, because the best deals go quick! I've been going to these events for the last 7 years, and, got lots of excellent deals on fishing, crabbing, boating gear. It's essentially more of a boating thing, but, lots of people bring their fishing gear to sell off, etc. It's the best garagesale for this type of gear you'll ever find! It's mad I tell you!
