Two Rivers Heritage Museum in Washougal, Washington
When you see this museum from the street, you might assume that it's a little one-room operation, but you couldn't be more wrong! Two Rivers is truly bigger on the inside, in a way that makes everyone remark, "It just keeps going...!" And this museum is jam packed with local history, but it's also brimming with all sorts of oddities. Ever seen a working player piano? How about art made entirely…
Still working mill you can tour with a factory outlet.
