1. 48 North / Fisheries Supply - Saturday, April 9 - Biggest and best event - across from Gasworks Park in seattle. The advertised time is 7:00 AM to 1:00 PM but my experience is that it really starts when I get there at 2:30 AM with my headlamp. There are some rumors of some sales the day before. If you get there at 7 AM, you will have to park a long walk away and the best spaces will be gone.2. Portland / West Marine - Saturday, April 30 - 8:00 AM to 2:00 PM at the Hayden Meadows store. These guys sleep in and get started at daylight. It is ok but not nearly as big as Fisheries.3. Swantown Boatswap in Olympia Washington - Saturday May 21 10:AM to 4:00 PM This event is kind of a dud in my experience. They charge for a 10 foot square bit of muddy grass in the park and you have to park several blocks away making it difficult for a one person sale.There are some others in Washington state - Everett, Bellingham, Port Townsend, Blaine, and Tacoma but I do not know when or where. If you know of one, how about posting it here?
