Part flea market, part hippie commune, part new-age commerce, the Georgetown Trailer Park Mall is one of the most unique shopping experiences in the Pacific Northwest. This unusual arrangement sees a number of retro trailers — including a vintage Airstream — used as storefronts for various businesses selling everything from vintage clothes and accessories to art, housewares, and even the occasional gadget. Open on Saturdays and Sundays, but if you happen to forget and show up on a typical Thursday afternoon, at least you can get some food from Where Ya At Matt.
